As reported on IRC by sephthir, the qemu_sparc_ss10_defconfig doesn't
work as expected: the system generated when booted under Qemu produces
illegal instruction messages.
gcc 8.3, 9.2 are the latest working gcc version. git bisect between
gcc 8.3 and 8.4 allowed to identify the commit that introcuced the
regression.
Reverting this patch allowed to produce a working rootfs.

As we many times by now discussed that - some ARC cores might
not have atomic instructions implemented. Namely that's ARC700
w/o explicitly added atomics during design creation/configuration.
Because of that when GCC gets configured for ARC700, i.e. via
"--with-cpu=arc700" atomic ops are assumed disabled.
Usually it's not a problem as we add "-matomics" in the wraper for
building all packages if targets CPU has atomis (BR2_ARC_ATOMIC_EXT).
But when bulding target's binaries which are essential parts of
the GCC itself we don't use the wrapper. Instead xgcc is being used.
That way we lose that important part of system's configuration about
atomics and:
1. Atomic ops won't be used where otherwise they could have been used.
2. Some configuration checks might end-up thinking there're no atomics
In particular (2) leads to pretty obscure failure on bulding of some
packages which use C++, for example:

...and many more.

used to be added in TARGET_{C|CXX}FLAGS via TARGET_ABI,
but later "-matomic" was moved to ARCH_TOOLCHAIN_WRAPPER_OPTS, see
https://git.buildroot.org/buildroot/commit/?id=c568b4f37fa6d7f51e6d14d33d7eb75dfe26d7bf
and since then we started to see that new breakage which we now
attempt to fix right where it hapens on GCC configuration.
In contrast ARC HS family has atomic ops enabled by default thus
we never spotted that kind of problem for it.

The GCC-7.x compiler series was the last to officially support PowerPC
SPE CPUs. Now that GCC-8.x is the default compiler used by Buildroot,
some defconfigs, notably the arcturus_ucp1020_defconfig and
freescale_p1025twr_defconfig ones started to fail building, as they
are PowerPC SPE platforms.
In fact, the GCC-8.x compiler series continues to support PowerPC SPE
CPU cores, but only as an --enable-obsoleted instruction set. This
patch enables the use of GCC-8.x and asserts the required option to
enable the PowerPC SPE instruction set.
This patch passes compilation and run tests with the
arcturus/ppc-ucp1020 board.
This patch should address a noted job failure on GitLab CI

The GCC package has a default conf option of disabling libquadmath and
the toolchain dependencies selectively enabled it if i386 / x64.
Fixes:
https://gitlab.com/bootlin/toolchains-builder/-/jobs/729359622
This patch fixes a build failure when (GCC + glibc) is being built for
the IBM Power8 arch and has libgfortran enabled + libquadmath disabled.
The libgfortran has a code condition for __float128 and includes the
quadmath headers. The bug occurs because Power8 has emulated
float128 support. The fix per GCC options is to also set
--disable-libquadmath-support which disables the
__float128/libquadmath support in gcc/fortran and in libgfortran [1].
Another option to fix the build failure was to enable libquadmath for
IBM Power8 (ISA 2.07), however this would be soft float based as the
ISA 3.0+ (Power9) first supports native float128 [2][3].

The logic in libbacktrace/configure.ac to detect if __sync builtins
are available assumes they are as soon as target_subdir is not
empty, i.e when cross-compiling. However, some platforms do not have

"libbacktrace_cv_sys_sync=no" is lost when it is added to

PowerPC has two PLT models: BSS-PLT and Secure-PLT. BSS-PLT uses
runtime code generation to generate the PLT stubs. Secure-PLT was
introduced with GCC 4.1 and Binutils 2.17 (base has GCC 4.2.1 and
Binutils 2.17), and is a more secure PLT format, using a read-only
linkage table, with the dynamic linker populating a non-executable
index table.

Back in commit [1], a patch fixing an issue a PowerPC issue in gcc was
added in gcc 4.3.3. It was present until gcc 4.9, which itself was
removed in [2]. The patch was dropped starting gcc 5.1 [3] but it's
know to be useful for gcc 4.7.3 [4]. However, even though we no longer
support building any of those older gcc versions, the conditional
patching logic in gcc.mk is still there.
We used to have a patch directory (package/gcc/$(GCC_VERSION)) for
every gcc version available in Buildroot, the apply-patches.sh script
doesn't error out even if
1000-powerpc-link-with-math-lib.patch.conditional is missing.
But with gcc 10, we don't need (for the moment) to apply any patch, so
the patch directory doesn't exist. apply-patches.sh breaks the build
since the patch directory is missing:
Aborting. 'package/gcc/10.1.0' is not a directory.
Since we removed gcc 4.9 last year [2], we can safely remove this code.
Tested using qemu_ppc_virtex_ml507_defconfig.

When the csky cpu support was added [1], the gcc download url was selected
depending on the csky cpu architecture (BR2_csky) rather than the csky gcc
fork version (BR2_GCC_VERSION_CSKY)[2].
When adding gcc 9.x version [3], we forgot to update the condition in order
to use the url to the gcc csky fork only when BR2_GCC_VERSION_CSKY=y.
Due to this error, the toolchain build with the upstream gcc 9.x for csky
cpu is broken due a download error.
Fix this by using BR2_GCC_VERSION_CSKY instead of BR2_csky.

This patch extends the "copy extra GCC libraries to target" feature to
also work for internal toolchains. The variable has been renamed to be
BR2_TOOLCHAIN_EXTRA_LIBS and the configuration option moved under the
generic toolchain package. For external toolchains, the step that does
the copy is still in the copy_toolchain_lib_root() helper which copies
from the sysroot to the target. For the internal toolchain, the host
gcc-final package does a post install hook to copy the libraries from
the toolchain build folders to both the sysroot and target(!static).
Examples where this can be useful is for adding debug libraries to the
target like the GCC libsanitizer (libasan/liblsan/...).

This error message come from a new check in binutils 2.32.x:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=f2c1801f6255a3f9f483ae2f07c7d7da0ddae4af
This issue has been reported on the uClibc-ng mailing list:
https://mailman.uclibc-ng.org/pipermail/devel/2019-August/001885.html
Since gcc 9.1 needs binutils 2.32.x or later to build successfully for
or1k, there is no binutils version left that can build gcc 9.1 and
uClibc.
For now, disable uClibc if gcc 9.1 is used for or1k.
