Set the toolchain's ARM CPU and FPU architectures by utilizing' gcc's
--with-cpu / --with-fpu configure options that: "Specify which cpu
variant the compiler should generate code for by default. cpu will
be used as the default value of the -mcpu= switch."
This will resolve the following kernel compilation failures under
gcc 8.x on ARM because the kernel wants to set (possibly conflicting)
optimization flags.
.../ccyVnmrs.s:204: Error: selected processor does not support `dmb ish' in ARM mode
.../ccyVnmrs.s:215: Error: architectural extension `mp' is not allowed for the current base architecture
.../ccyVnmrs.s:216: Error: selected processor does not support `pldw [r4]' in ARM mode
Because this is a big change, the .config and toolchain need to be
refreshed (as in removed and regenerated).

Commit e61061a0886e2d0d6b075d75ae9b53d0a6bc9042 added support for hardening
options in the toolchain. However this breaks the gcc5.5.0 compilation in
case FORTIFY_SOURCE is set different from FORTIFY_SOURCE_NONE as reported
in [1].
Fix this by backporting the upstream patch which fixes this in later gcc versions

Changes compared to GCC 7.x
001-revert_register_mode_search.patch dropped
The underlying issue is described at the end of
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58139
It is fixed by the upstream commit:
https://github.com/gcc-mirror/gcc/commit/3fa2798aa887d141d86985240f03e2f3809e7e62
020-PR-libstdc-81797-Add-.NOTPARALLEL-to-include-Makefil.patch dropped due to already upstream
100-PR-rtl-optimization-83496.patch dropped due to already upstream
910-mbsd_multi.patch
modified to fix ambiguous overloaded inform() call error
gcc/input.h
header: define UNKNOWN_LOCATION ((source_location) 0)
- inform (0, "someone does not honour COPTS correctly, passed %d times",
- honour_copts);
+ inform (UNKNOWN_LOCATION, "someone does not honour COPTS correctly, passed %d times",
+ honour_copts);
940-no-clobber-stamp-bits.patch dropped due to fixed upstream by another way
upstream commit: https://github.com/gcc-mirror/gcc/commit/87b2d547f8ac9778d66909b8726fe967d1efbc74
950-cpp_file_path_translation.patch dropped, Both -fmacro-prefix-map and -ffile-prefix-map are added
to gcc 8.1.0, if I understand it correctly, we should use -fmacro-prefix-map
usage: -fmacro-prefix-map=@var{old}=@var{new}
upstream commit: https://github.com/gcc-mirror/gcc/commit/859b51f83662d01e4f158ea9327db9ca37fe70b3
-iremap exists as a flag for a long time, for backward compatibility, I think we should keep the
variable name unchanged but change its value in rules.mk for gcc 8.x and higher.

Newer GCC versions are reported to improve code size on various ARM
devices, which is why newer u-boot versions require them now.
There have also been user reports of data corruption issues fixed on
MIPS by updating from GCC 5 to GCC 7.
This update was previously held up by these two MIPS compile issues,
which have since been fixed:

Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh,
avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain
and depends it means 'build gcc with libssp'.
Musl no longer uses libssp (1877bc9d8f), it has internal support, so
SSP_SUPPORT was disabled leading some package to not use SSP.
No information why Glibc and uClibc use libssp, but they may also provide
their own SSP support. uClibc used it own with commit 933b588e25 but it was
reverted in f3cacb9e84 without details.
Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT
if either USE_MUSL or GCC_LIBSSP.

This fixes GCC 7 compilation when GRAPHITE is selected.
The path is replaced with $(TOOLCHAIN_DIR), while it should be
$(STAGING_DIR_HOST). To keep in sync with the path of gmp,

arc-2016.09 is the most recent toolchain for ARC cores and
it is based on top of upstream Binutils 2.27 and GCC 6.2.1.
With updated major version of GCC we copied all GCC 6.x patches
for ARC as well as Bintils 2.27 patches.
Note that toochain sports ARCv4 ABI and so must be used
with 4.8+ Linux kernels. Even though it will build v4.4 kernel
perfectly fine on attempt to run user-space apps they won't
work with older kernel. That said previuosly sent RFC patches with
Linux kernel update are required:

On attempt to build ARC toolchain on the host with gcc 6.1 I saw the
same failure as described in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69959
This change adds a back-port of the fix from upstream gcc, see
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=233572
Note the fix is already a part of gcc-5.4 and gcc-6.1 so no need for
the same fix for others.
