At configuration time, gcc assumes that ppc64be targets use the ELFv1
ABI, and ppc64le targets use the ELFv2 ABI. However, musl libc does not
support the ELFv1 ABI on ppc64 at all, regardless of the endianness.
Therefore, when building for a ppc64 arch and with musl libc, instruct
gcc to use the ELFv2 ABI.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93157 for more info.

This patch has been upstream since GCC 10.

Add backport patch to define TARGET_LIBC_GNUSTACK on musl to add

The net effect should be the exact same functionality while following
upstream code instead of a custom outdated patch.

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.

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 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).
