We have a toolchain wrapper for external toolchain, but it is also
beneficial for internal toolchains, for the following reasons:
1. It can make sure that BR2_TARGET_OPTIMIZATION is passed to the
compiler even if a package's build system doesn't honor CFLAGS.
2. It allows us to do the unsafe path check (i.e. -I/usr/include)
without patching gcc.
3. It makes it simpler to implement building each package with a
separate staging directory (per-package staging).
4. It makes it simpler to implement a compiler hash check for ccache.
The wrapper is reused from the external toolchain. A third CROSS_PATH_
option is added to the wrapper: in this case, the real executable is in
the same directory, with the extension .real.
The creation of the simple symlinks is merged with the creation of the
wrapper symlinks, otherwise part of the -gcc-ar handling logic would
have to be repeated.
The complex case-condition could be refactored with the one for the
external toolchain, but then it becomes even more complex because
they each have special corner cases. For example, the internal
toolchain has to handle *.real to avoid creating an extra indirection
after host-gcc-{final,initial}-rebuild.
Instead of creating the .real files, it would also have been possible
to install the internal toolchain in $(HOST_DIR)/opt, similar to what
we do for the external toolchain. However, then we would also have to
copy things to the sysroot and do more of the magic that the external
toolchain is doing. So keeping it in $(HOST_DIR)/usr/bin is much
simpler.
Note that gcc-initial has to be wrapped as well, because it is used for
building libc and we want to apply the same magic when building libc.

The toolchain wrapper will be reused for the internal toolchain, so it
belongs in the toolchain directory. Also, the ext- prefix is removed
from it. The build commands are moved to a new toolchain-wrapper.mk.
The wrapper arguments that are also relevant for the internal toolchain
wrapper are moved to toolchain-wrapper.mk, the rest stays in
toolchain-external.mk.
While we're at it, move the building of the toolchain wrapper to the
build step of toolchain-external. There is no specific reason to do
this, other than that it fits better semantically. Also remove the
MESSAGE call, otherwise we'd see:
>>> toolchain-external undefined Building
>>> toolchain-external undefined Building toolchain wrapper
/usr/bin/gcc ...
Having an extra "Building toolchain wrapper' message is pointless.
The useless condition on $(BR2_TARGET_OPTIMIZATION) is removed. It was
always true because it wasn't qstrip'ped first, so clearly it works
without that condition as well.
Also rewrapped some comments and removed the 'external' reference.

The FOO_SITE/FOO_SOURCE variables usually point to a tarball containing
source code.
For the downloaded external toolchains this is not true, the "source"
tarball actually contains binaries. This is fine for making Buildroot
work, but for legal-info we really want to ship real source code, not
binaries.
Luckily, some (hopefully all) toolchain vendors publish a downloadable
tarball containing the source code counterpart for their binary
packages.
Here we allow the user to declare the URL of this other tarball in the
pair of variables FOO_ACTUAL_SOURCE_TARBALL (by default equal to
FOO_SOURCE) and FOO_ACTUAL_SOURCE_SITE (by default equal to FOO_SITE).
If the "actual source" package can be downloaded from the same
directory as the binary package, then only FOO_ACTUAL_SOURCE_TARBALL
needs to be set.
Note this change is not strictly toolchain-specific: it might be useful
for other packages that happen to ship binaries in the same way.

A trailing slash in FOO_SITE is useless, since Buildroot automatically adds
a slash between FOO_SITE and the filename as appropriate.
Moreover it is potentially harmful, which led to introducing a workaround
to strip them:
commit 1cbffbd015
Author: Shawn J. Goff <shawn7400@gmail.com>
Date: Fri Apr 12 09:40:30 2013 +0000
eliminate double slashes caused by FOO_SITE ending in a slash
When a FOO_SITE variable ends in a slash and gets joined with a
FOO_SOURCE variable like $(FOO_SITE)/$(FOO_SOURCE), the resulting URI
has a double slash. While double-slashes are fine in unix paths, they
are reserved in URIs - the part following '//' must be an authority.
So let's ban trailing slashes entirely. They have all been removed in
a 7b0e757fb8, now add a check to error out loudly in case a new one
is added.
Example commands to test this check:
$ make busybox-dirclean busybox-source
rm -Rf /home/murray/devel/buildroot/output/build/busybox-1.23.2
busybox-1.23.2.tar.bz2: OK (md5: 7925683d7dd105aabe9b6b618d48cc73)

Trailing slashes are going to be declared illegal from FOO_SITE
variables.
But Buildroot internally generates such a variable when using a custom
external toolchain (i.e. BR2_TOOLCHAIN_EXTERNAL_CUSTOM). This is
because TOOLCHAIN_EXTERNAL_SITE is set to
$(dir $(call qstrip,$(BR2_TOOLCHAIN_EXTERNAL_URL))), and $(dir)
leaves a trailing slash.
Fix it using patsubst, just like linux and the bootloaders do.

FreeRDP uses CMSPAR, which is defined by glibc in bits/termios.h .
glibc has two flavours of bits/termios.h: a genmeric one and an
architecture-specific one. When installing, glibc will install the
architecture-specific file if it exists, otherwise it installs the
generic file. Only Alpha, MIPS, PPC and Sparc have their own
bits/termios.h.
The generic bits/termios.h, as well as the Alpha, PPC and Sparc flavours
do define CMSPAR. However, the MIPS flavour does not define it.
We add a patch to FreeRDP that defines CMSPAR to the value from the
generic value, which is also the value known to the Linux kernel for
MIPS.

swupdate provides a reliable way to update the software on an embedded system.
Note that swupdates has a reworked Kbuild/Kconfig system. It has now support
for the 'option' and 'env' symbols as well for the 'savedefconfig' target.
This makes dependency handling much easier. We're now able to pass which
dependencies are available through the environment, as suggested by Arnout
Vandecappelle [1].
In previous version of this patch we had a configuration setting where all
package dependencies except Lua were selected by default. This has changed with
v7 as we are now able to pass dependencies to the swupdate build system through
the environment. For useful operation swupdate requires a parser which depends
by default on libconfig, but can be replaced by a json-c or Lua parser.
To provide a reasonable firmware update system we enable the embedded webserver
based on mongoose (also see notes about mongoose below), a parser as stated
above and a handler for raw NAND or NOR flash.
The user can modify this configuration by selecting the appropriate dependencies
before running `make swupdate-menuconfig`. The help text contains information
about which packages may be of interest for the user.
The embedded web server requires a website for proper operation. We install the
included website by default, however the user may choose to install a custom
website on the post-build scripts.
Note, swupdate includes some old versions of mongoose and lsqlite3:
- mongoose is version 3.8 from year 2013
- lsqlite3 is version 0.8 from year 2011
Currently, swupdate does not provide a way to replace these with external
packages.
This patch is based on a WIP version submitted by Romain Naour, commented by
Arnout Vandecappelle [2].

However this is broken when static /dev management is selected and the root

When Valgrind detects a 32-bit MIPS architecture, it forcibly adds
-march=mips32 to CFLAGS; when it detects a 64-bit MIPS architecture, it
forcibly adds -march=mips64. This causes Valgrind to be built always for
the first ISA revision level (R1), even when the user has configured
Buildroot for the second ISA revision level (R2).
Since R2 is backwards compatible with R1, you can run a Valgrind built
for R1 in an R2 core. This is why nobody noticed about this problem, or
at least nobody complained.
But, since (I hope) we will support R6 in Buildroot in the near future,
this problem will become very important because R6 is not backwards
compatible with R1 or R2, so building Valgrind for R1 when your target
is R6 will result in a non-working Valgrind.
Override the CFLAGS variable (which Valgrind appends to its CFLAGS) and
pass the right -march option, so they take precedence over Valgrind's
wrongfully detected value.
