Raise the minimum GCC version to 12.1 [BZ #32539]
For all Linux distros with glibc 2.40 which I can find, GCC 14.2 is used
to compile glibc 2.40:

Support older versions of GCC to build glibc 2.42:
1. Need to work around bugs in older versions of GCC.
2. Can't use the new features in newer versions of GCC, which may be
required for new features, like _Float16 which requires GCC 12.1 or
above, in glibc,
The main benefit of supporting older versions of GCC is easier backport
of bug fixes to the older releases of glibc, which can be mitigated by
avoiding incompatible features in newer versions of GCC for critical bug
fixes. Require GCC 12.1 or newer to build. Remove GCC version check for
PowerPC and s390x.
TEST_CC and TEST_CXX can be used to test the glibc build with the older
versions of GCC.
For glibc developers who are using Linux OSes which don't come with GCC
12.1 or newer, they should build and install GCC 12.1 or newer to work
on glibc.
This fixes BZ #32539.
