This adds another mode to do_gcc_core_backend that builds libstdc++
against an alternate libc implementation.

1. Allows picolibc's stdio to be used with c++ applications
2. Includes arm exception information in link rules
3. Adds picolibc include directory to c++ header paths.
These patches are all upstream in picolibc and included in version
1.5.

If we are targetting an aarch64-none-elf toolchain we end up running
into a build issue in gcc/config/aarch64/driver-aarch64.c. This is
fixed in upstream gcc so just backport the patch to gcc-10.2.0

When building aarch64-unknown-linux-gnu on MacOS X, aarch64-builtins.c
files doesn't build by default with clang on MacOS X. We need to pass
-std=gnu++11 when building the file for things to work with clang.

Expect that if there is a binutils 2.35.2 release these fixes will be
included in there, these are pulled out of the binutils-2_35-branch post
the 2.35.1 release.

Backport change from glibc upstream that defines RELEASE as stable
instead of release. This will at least cause the default_cflags to be
set to expected default values again.
Ref issue #1396, although the bigger issue of respecting crosstool-ng
CT_GLIBC_EXTRA_CFLAGS is most likely still not fixed.

This seems to only trigger for powerpc64. Other architectures build
cleanly. For now avoid specifying -Werror for powerpc64+glibc-2.32.
