glibc-2.23 fails to build for mips with
nptl/libpthread.so:(*IND*+0x0): multiple definition of `vfork@GLIBC_2.0';
This was fixed in glibc-2.24. Backport the fix for glibc-2.23.

glibc 2.12.1 was marked as obsolete. Now that the 1.25.0 release is out
this version can be removed completely. As glibc 2.12.1 was the last
remaining version supported by glibc-ports support for glibc-ports is
also removed.

Newer GCC versions trigger warnings on older GLIBC versions. GLIBC 2.29
is warning free with GCC9. GLIBC 2.31 is warning free with GCC10. GLIBC
2.34 is warning free with GCC11.
Add milestones for 2.31 and 2.34 and use those to set the default value
for GLIBC_ENABLE_WERROR based on the GCC version.

CentOS6 has reached EOL so now glibc-2.12.1 can be marked as obsolete.
This also means the last glibc-ports version (and glibc-ports itself)
obsolete as well. These will be removed after the next release.

This refreshes the line numbers, removes any fuzz (which would make any
future forward ports easier) and standardizes the patch/file headers
(which makes them easier to read).

Otherwise, it tries to link against libgcc_eh which is not available
until the final compiler (or previously, the pass-2 compiler) is built.

Copied patches from glibc version 2.34, they still apply clean and I

As of today ARCompact (AKA "ARCv1 ISA") processors (mostly those are ARC770)
are not officially supported by upstream glibc as it adds quite some burden
on release ans support of yet another "architecture" port.
But given on ABI and ISA front ARCompact is very close to ARCv2 we may
easily retrofit its support off-the-tree, which we do here.
Also given amount of changes we need to apply there's a hope it will be easy
and straight-forward to apply the same to later versions of glibc.

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.

Forward ported 0000-typedef-caddr.patch from previous release (2.31).
Dropped the 0001-Add-ARC-architecture.patch file, since ARC support is
included in glibc release 2.32.

So again due to non-technical reasons (lack of public documentation
of ARC instruction set which we actively work on but no yet published)
we missed upstream 2.30 release.
Still the code is there, we regularly run full test-suite and are confident
in port's quality and robustness.

ARC port of Glibc was submitted to the mailing list recently [1]
but due to late submission it didn't make it in Glibc 2.29 release.
Hopefully by the time of next release it will be a part of upstream
release but for now we have to use off-the-tree patch.
Still it's proven to work internally as well as its test-suite
shows brilliant results as might be seen from [1]:
------------------>8-------------------
Summary of test results:
24 FAIL
5124 PASS
27 UNSUPPORTED
19 XFAIL
------------------>8-------------------
Moreover ARC's Glibc port is known to work in Buildroot, OpenEmbedded
and even Automotive Grade Linux distro so we should be good having
this patch for Glibc.
BTW the patch itself is a copy of the one I use in OE, see [2].

- Force building make as a companion tool if host make is older than
4.0 (CentOS 7 currently has 3.82)
- Disable 2.29 as a choice if host python is older than 3.4
(CentOS 7 has 2.6 unless python from EPEL is installed)
- Python2 emits its version information to STDERR. Ugh.
While there, also use the detected host Python for GDB configuration.

- GLIBC requires a fix to work with binutils 2.30 on aarch64. This fix
relies on binutils 2.24 or newer, which is okay for glibc 2.26 since
it needs 2.25 or newer anyway. But older glibc versions are now pinned
to binutils 2.29 or older on aarch64.
