GCC 5.1 changed the std::string ABI in order to properly support C++11.
For compatibility with libraries compiled with the older ABI, that is,
linking between old-abi.so and new-abi.bin, both ABIs are enabled. In
terms of OpenWrt, all packages are compiled with the same toolchain,
which means these issues do not need to be handled.
Most importantly, this results in a significant size reduction of
libstdpp:
Before:
450794 bytes
After:
327752 bytes
Tested with all OpenWrt packages.

GCC was used in 17.01 as the default compiler the last time. We do not
test this old GCC version any more and there are some known problems it
fails to compile the U-Boot for the Allwinner A64 SoC.
Just remove it to make it clear that we will not support this old GCC
version any more.

Removes the standalone implementation of stack smashing protection
in gcc's libssp in favour of the native implementation available
in glibc and uclibc. Musl libc already uses its native ssp, so this
patch does not affect musl-based toolchains.
Stack smashing protection configuration options are now uniform
across all supported libc variants.
This also makes kernel-level stack smashing protection available
for x86_64 and i386 builds using non-musl libc.

This backports the patch for GCC PR target/89587 (gcc's rs6000
configuration unconditionally sets MULTIARCH_DIRNAME, even when
multiarch is disabled).
This currently affects apm821xx and may cause issues when
cross-compiling packages, e.g. Python 3[1].
This includes patches for GCC 8 (with the changelog diff removed);
this change is already included in GCC 9.2 and 7.5.

The following patches are backported from the GCC 9.X development branch:

toolchain/gcc/patches/9.1.0/975-g++-ICE-with-generic-lambda.patch

This problem exposed when compiling glibc, but applicable across the
board. gcc compiles runtime libraries for all supported architectures,
unless otherwise specified, and later selects applicable library based
-m[arch,cpu,*] options, thus these options should not be passed to gcc
as they break the compilation process.

[modified so it only touches ARM - I'm too chicken, changed authors email]
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).

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.
