Add GCC 12 

The latest version of GCC.
And with this, the glibc-musl-gcc toolchain is complete.

A variety of modern features (default PIE SSP) are enabled.

==========
This is the most recent version of GCC. With this version of GCC, the
final gcc-binutils-musl toolchain is complete. The focus of further builds
shifts to rebuilds for correctness, cleanup and preparation for downstream
consumption.
In line with this, a variety of modern features + minor build changes are used
to ensure the compiler is suitable for downstream consumption;
* A full internal GCC bootstrap is used to ensure there are no lagging
historical problems.
* PIE and SSP are enabled by default, as is done on every major modern Linux
distribution.
* libssp is disabled and handed off to the libc (done by many modern Linux
distributions). libssp in GCC is very broken and glibc-centric - it should
really be handled by the libc, which is what most distributions do.
* LTO now fully functions correctly, despite both the linker and the compiler
being static binaries.

With that, we may then run plain 'autoreconf' for all of GCC's subpackages,
instead of for some of those (that don't use Automake) manually having to run
the applicable combination of 'aclocal', 'autoconf', 'autoheader'.

The original motivation from this patch from Alpine Linux:
Subject: [PATCH] Alpine musl package provides libssp_nonshared.a. We link to
it unconditionally, as otherwise we get link failures if some objects are
-fstack-protector built and final link happens with -fno-stack-protector.
This seems to be the common case when bootstrapping gcc, the piepatches do
not seem to fully fix the crosstoolchain and bootstrap sequence wrt.
stack-protector flag usage.
Which matches precisely the problem when compiling GCC with --enable-bootstrap
in live-bootstrap.
