When building powerpc64+glibc-2.32 we see the following error:

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

The same binaries are now hosted on GitHub releases (and looking at the
homepage, that's the only download location they are offering). Use that
mirror at least as an option.
When GCC was updated to 8.4.0 the patches were moved incorrectly. Fix
this now so that they will be picked up.

Two patches from 0.18.8.1 were dropped:
- one changing the declaration of environ is no longer needed, the
corresponding files no longer have this declaration
- one with Woe32 fixes for -O0 may need to be re-added but only after I
find what configuration breaks without it; gettext sources overwent a
massive restructuring so this patch should not be applied without
testing.

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.

Currently, SourceForge is down and downloads give a 500 error. That's
not overly uncommon (even less often the case these days). Fortunately,
zlib provides another mirror on their homepage, add that as option to
the package description. (https://www.zlib.net/)
Forward ported patches from GCC 8.3.0 to 9.2.0, refreshed to match
current sources.
In patch 0012-crystax.patch, removed changing sysv4.h header file for
rs6000, since it no longer defines LINK_EH_SPEC.
Removed the following patches because they are part of upstream:
- 0018-ARC-Add-multilib-support-for-linux-targets.patch
- 0020-ARM-fix-cmse.patch
- 0021-arm-Make-arm_cmse.h-C99-compatible.patch
- 0022-ARC-Update-fma-expansions.patch
Renamed 0019-isl-0.20.patch => 0018-isl-0.20.patch.

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].

Older GCCs (e.g. GCC 4.4 in CentOS 6) chokes on having two identical
typedefs like this:
typedef void *p;
typedef void *p;
The event-loop.h header does not have a guard against double-inclusion.
Not the best solution, but it works and eventually 7.12 will fall into
obsolescence anyway.

- 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.
