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.

From GCC's standpoint ARC's multilib items are defined by "mcpu" values
which we have quite a few and for all of them might be built optimized
cross-toolchain.
From Glibc's standpoint multilib is just multi-ABI [1] and so very limited
versions are supposed to co-exist (e.g. arc700 & archs).
Here we force Glibc to install libraries in GCC's multilib folder to create
a universal cross-toolchain that has libs optimized for multiple CPU types.
But note we only need to mess with installation paths in case of real
multilib, otherwise we keep default "lib/" paths so that GCC finds default
(the one and only) libs where it expects them to be.
Also here we add a sample which allows to build universal Glibc Linux
toolchain for ARC.

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].

uclibc_backend_once tries to build dummy shared libraries regardless of
whether shared libraries support for target is enabled or not, resulting
in build failure in noMMU bFLT configuration.
Only build dummy shared libraries when shared library support for target

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.
