My earlier change broke Solaris testing, because @FLOCK@ isn't substituted
just into libgomp/Makefile where it worked, but also the
testsuite/libgomp-site-extra.exp file where Make variables aren't present
and can't be substituted.
The following patch instead computes the absolute srcdir path and uses it
for FLOCK.

(cherry picked from commit 2fb3ee3ee8)
When flock program doesn't exist, libgomp configure attempts to
offer a fallback version using a perl script, but we weren't using
absolute filename to that, so it apparently failed to work correctly.
The following patch arranges for it to get the absolute filename.

During the Sphinx-migration development, I used
SPHINX_BUILD='' in order to skip building info and manual
pages in gcc folder. However, we've got HAS_SPHINX_BUILD
which is the correct flag for that.
With the patch, one will get a nicer error message when
sphinx-build is missing and one builds (explicitly) a target which
depends on it.

This change adds the configury bits to activate the build of
shared libs on VxWorks ports configured with --enable-shared,
for libraries variants where this is generally supported (rtp,
code model !large - currently not compatible with -fPIC).
Set lt_cv_deplibs_check_method in libtool.m4, so the build of
libraries know how to establish dependencies. This is useful in
configurations such as aarch64 where proper support of LSE relies
on accurate dependency information between libstdc++ and libgcc_s
to begin with.
Regenerate configure scripts to reflect libtool.m4 change.

Instead, unconditionally built against the GCC-shipped 'include/hsa*.h' header

When building an nvptx offloading configuration on openSUSE Leap 15.3, the
site script /usr/share/site/x86_64-unknown-linux-gnu is activated, setting
libexecdir to ${exec_prefix}/lib rather than ${exec_prefix}/libexec:
...
| # If user did not specify libexecdir, set the correct target:
| # Nor FHS nor openSUSE allow prefix/libexec. Let's default to prefix/lib.
|
| if test "$libexecdir" = '${exec_prefix}/libexec' ; then
| libexecdir='${exec_prefix}/lib'
| fi
...
However, in libgomp libgomp/plugin/configfrag.ac we hardcode libexec:
...
# Configure additional search paths.
if test x"$tgt_dir" != x; then
offload_additional_options="$offload_additional_options \
-B$tgt_dir/libexec/gcc/\$(target_alias)/\$(gcc_version) \
-B$tgt_dir/bin"
...
Fix this by using /$(libexecdir:\$(exec_prefix)/%=%)/ instead of /libexec/.

The depend type is a struct with two pointer members for C/C++ - but for
Fortran OpenMP requires an integer type with kind = omp_depend_kind. Thus,
libgomp's configure checks that an integer type/kind with size 2*sizeof(void*)
is available. However, this integer type/kind is not needed when building without
Fortran support. Thus, only check this when Fortran is enabled.

As recently again discussed in <https://gcc.gnu.org/PR97436> "[nvptx] -m32
support", nvptx offloading other than for 64-bit host has never been
implemented, tested, supported. So we simply should buildn't the nvptx libgomp
plugin in this case.
This avoids build problems if, for example, in a (standard) bi-arch
x86_64-pc-linux-gnu '-m64'/'-m32' build, libcuda is available only in a 64-bit
variant but not in a 32-bit one, which, for example, is the case if you build
GCC against the CUDA toolkit's 'stubs/libcuda.so' (see
<https://stackoverflow.com/a/52784819>).
This amends PR65099 commit a92defdab7 (r225560)
"[nvptx offloading] Only 64-bit configurations are currently supported" to
match the way we're doing this for the HSA/GCN plugins.

The change in major version (and the increment from Darwin19 to 20)
caused libtool tests to fail which resulted in incorrect build settings
for shared libraries.
We take this opportunity to sort out the shared undefined symbols state
rather than propagating the current unsound behaviour into a new rev.
This change means that we default to the case that missing symbols are
considered an error, and if one wants to allow this intentionally, the
confiuration for that case should be set appropriately.
Three existing cases need undefined dynamic lookup:
libitm, where there is already a configuration mechanism to add the
flags.
libcc1, where we add simple configuration to add the flags for Darwin.
libsanitizer, where we can add to the existing extra flags.

This patch removes the generation of HSAIL from the compiler, the HSA
offloading plugin from libgomp and the associated testsuite tests and
infrastructure bits from the respective testsuites.
Apart from removal of the obvious files, I removed bits that I found
by searching for HSA related terms and by re-tracing my steps and
looking at the patches that introduced HSA in the first place. I did
not remove everything these patches brought in, for example:
- the mechanism to pass offload-target specific info from the application to
the offloading plugin - but the same mechanism is also used to
communicate number of teams and the thread limit to all offload targets.
- run_func hook in gomp_device_descr stays too, although now it is
not used. If some future offload target would like the ability to
refuse to offload some functions, it can use it. It is easy to
remove as a follow-up if it is considered clutter, though.
- configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH
and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too.
- Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant
from gomp-constants.h) appears in the source of the amdgcn libgomp
plugin, although I tend to think that code path is not ever used
and this patch certainly removes it from the compiler.
Nevertheless, it seems it has potential value beyond HSAIL and so
I've kept it, it can of course always be easily removed in the
future of GCN folk abandon it too.
- I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA
need to stay indefinitely too just so that no future offload
target picks that number.
- I have kept dg-require-effective-target
offload_device_nonshared_as requirement of thests which have it.
It is quite probable I missed some small HSA artifacts but those
should be easy to remove later as we find them.

This patch adds the ability to configure GCC on AIX to build as a
64 bit application and to build target libraries "FAT" libraries in both
32 bit and 64 bit mode.
The patch adds makefile fragment hooks to target libraries that allows
them to include target-specific rules. The target specific rules for
AIX place both 32 bit and 64 bit objects and shared objects
in archives at the top-level, not multilib subdirectories. The
multilibs are built in subdirectories, but must be combined during the
last parts of the target library build process. Because of the way
that GCC bootstrap works, the libraries must be combined during the
multiple stages of GCC bootstrap, not solely when installed in the
final destination, so the libraries are correct at the end of
each target library build stage, not solely an install recipe.

Fix a problem with commit c8e759b421 ("libgomp/test: Fix compilation
for build sysroot") that caused a regression in some standalone test
environments where testsuite/libgomp-test-support.exp is used, but the
compiler is expected to be determined by `[find_gcc]', and set the
GCC_UNDER_TEST TCL variable in testsuite/libgomp-site-extra.exp instead.
