This commit introduces few related changes which need to be done in
single commit to keep images buildable between git revisions. In result
it retains all previous image creation possibilities with slight name
change of generated images. Brief summary of the commit:
* Split up image generation recipe to smaller chunks to make it more
generic and reusable.
* Make iso images x86 specific and drop their definition as root
filesystem.
* Convert image creation process to generic code specified in image.mk.
* Make geode subtarget inherit features from the main target instead of
redefining them.
* For subtargets create device definitions with basic packages set.

IMAGE_SIZE is widely used in many targets. Declare it in the default template to
clean up redundant code. This also prevents deriving IMAGE_SIZE unintentionally
from the previously defined device.
While at it, remove duplicate KERNEL_SIZE declaration.

getopt is the only command where /usr/local/bin is specified explicitly.
All other commands are assumed to exist in the PATH in one form or
another. Remove this exception and require gnugetopt/getopt to be in
the user's PATH.
In the case of macos Homebrew, getopt is 'keg only' hence not linked
into /usr/local/bin whilst other commands are linked and likely found by
virtue of /usr/local/bin being in PATH.
Since 2019 Homebrew is very reluctant to install links that have
potential to override default OS behaviour, eg: following instructions
on our current 'how to build on macos' wiki page:
$ brew ln gnu-getopt --force
Warning: Refusing to link macOS-provided software: gnu-getopt
If you need to have gnu-getopt first in your PATH run:
echo 'export PATH="/usr/local/opt/gnu-getopt/bin:$PATH"' >> ~/.zshrc
A better option for macos is to link getopt as 'gnugetopt' in
/usr/local/bin, thus the build system will find 'gnugetopt' but other
applications looking for just 'getopt' will find the original macos
binary.
Ultimately it makes sense that 'GNU' dependencies are placed in
/usr/local/bin and /usr/local/bin is included in the user's PATH.

Build/InstallDev no longer places a file list in
$(STAGING_DIR_HOST)/packages; this change removes the creation of
$(STAGING_DIR_HOST)/packages and the attempted removal of a
STAGING_DIR_HOST file list during package clean.
This also changes the host directory passed to Build/UninstallDev from
$(STAGING_DIR_HOST) to $(STAGING_DIR)/host, to match the directory
passed to Build/InstallDev.

Build system needs an 'xargs' that supports '-r' which darwin doesn't.
Homebrew installs a 'gxargs' with the findutils package so look for
'gxargs' as well as 'xargs'
This is a bit of a 'fun' corner case anyway. xargs is only required by
the build if 'CONFIG_AUTOREMOVE' is set and after the build system has
built 'tools/findutils' we have a fully working xargs for host anyway.
Until that time we have to rely on the host's xargs implementation.

Certain boards have limitations on U-Boot that prevent flashing
of images where the kernel size exceeds a threshold, yet
sysupgrade can sucessfully manage larger kernels. The current
check-size will remove the target artifact if its total size
exceeds the threshold. If applied after append-kernel,
it will remove the kernel, but the remaining image-assembly
steps will continue, resulting in an image without a kernel
that is likely unbootable.
By defining check-kernel-size, it is now possible to prevent release
of such unbootable images through a construct similar to:
IMAGE/factory.img := append-kernel | pad-to $$$$(GL_UBOOT_UBI_OFFSET) | \
append-ubi | check-kernel-size $$$$(GL_UBOOT_UBI_OFFSET)

This tristate choose allows to select to build only some applications
with PIE enabled. On MIPS binaries are getting about 30% bigger when PIE
is activated for the, which is a huge increase.
Network exposed applications like dnsmasq should then be build with PIE
enabled, but some applications which are normally not parsing data from
the network do not have it activated. The regular option should give a
good trade off between extra flash and RAM memory usage and security.
This changes the default from building no applications with PIE to build
some specifically marked applications with PIE enabled. This option is
only activated for targets with bigger flash and RAM to not consume
extra memory on the very small targets. On SDK builds the Regular option
should always be selected, because some tiny targets share the
applications with big targets and only the images for the tiny targets
should contain the none PIE applications, but the images for the normal
targets should use PIE. The shared packages should always use PIE when
it should be normally activated.

This move the slightly different target-specific implementations of
mktplinkfw from the targets to include/image-commands.mk and renames
it to tplink-v1-image. Having a common version will increase
consistency between implementation and will complete the
tplink build command already present in the new location.
Due to the slight differences of the original implementations, this
also does some adjustments to the device build commands/variables.
This also moves rootfs_align as this is required as dependency.

Currently in OpenWrt, there are two libc++: libstdcpp and uClibc++. The
former is huge and the latter supports only C++98 with some basic support
for C++11. Those C++ versions seem to be specific to the compiler version
libcxx supports C++11 and above while being much smaller than libstdcpp.
On mt7621, these are the sizes of the ipks that I get:
libstdcpp: 460786
libcxx: 182881
uClibc++:67720
libcxx is faster than uClibc++ and is under active development as part of
the LLVM project while uClibc++ is effectively dead.
This PR modifies uclibc++.mk to expose the make menuconfig option. Further
cleanup is beyond the scope of this PR. What that means is, this is not
used by default.
A g++-libcxx wrapper based on the uClibc++ one was added. Works the same
way.
Compile tested with all packages that use uclibc++.mk in their Makefiles
under mipsel_24kc. kismet fails compilation but that package needs to be
cleaned up and updated.

Commit 965f341aa9 ("build: fix host menu config targets using

the first place in PATH variable, which is now causing issues with bison
as BISON_PKGDATADIR points into STAGING_DIR_HOST, but the actual bison
used is the one under host PATH (usually /usr/bin/bison), leading to the
following strange failures:

Replace 2 instances of non posix use of 'head' with posix compliant
'cut'.
'head -c n' cuts 'n' bytes from the passed string and happens to work on
Linux & Mac OS X even though '-c' is not posix.
'head --bytes n' does the same thing and happens to work on linux but
not on Mac OS X and is also not posix.
'cut -b1-8' cuts the first 8 bytes from the passed string and is posix
compliant, hence works on Linux & Mac OS X.
Our usage of 'head --bytes' was particularly unfortunate since it was
used to calculated the RootFS UUID passed to grub - the net result being

On a recent Gentoo Linux installation, invoking `make menuconfig`, `make
kernel_menuconfig` or `make kernel_nconfig` in the build system fails,
whereas for example `make menuconfig` in the kernel tree alone works as
expected.
This is happening because STAGING_PREFIX is not defined when kernel's
{menu,n}config target calls pkg-config from the toolchain/host and thus
pkg-config returns an empty value, and the fallback values in the kernel
config script are applied but those are off and the linking fails.
Solution is to use system's pkg-config for all ncurses based menu config
targets in order to provide proper compiler/linker flags.
