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.

ftp://invisible-island.net/ncurses doesn't actually have the numbered
ncurses tarball. We've not noticed because we fall back to using the GNU
mirror which does. It's also ftp which is being deprecated.
Switch to https://invisible-mirror.net/archives/ncurses which has the
actual tarballs and provides a secure connection.

Backport change from glibc upstream that defines RELEASE as stable

CT_GLIBC_EXTRA_CFLAGS is most likely still not fixed.

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

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.
