I was trying to build static binaries for a range of Broadcom soft-float ARMv7
SoCs and kept getting SIGILL, although I was targeting Cortex A7 (and A5,
later), even on A9 and A15.
I found out that once I add -msoft-float, +mp+sec is to blame:

I kept getting SIGILL even after building my application with a toolchain built
with the correct CFLAGS and found out that crosstool-ng doesn't pass the host
CFLAGS when building musl, which pollutes my binary with these ARMv7 extensions.

The glibc will append the content of the CFLAGS variable,
overriding previous flags.
If unset, the CFLAGS variable is not empty, so explicitly set it.
Instead prepend the default CFLAGS flags.

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.

On some systems the file command identifies a pie executable as a shared
object. Update do_finish() to handle this case so that they are stripped
as well.

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.

Per the release notes for the GNU C library 2.28[1] make 4.0 or newer is
required. Previously the logic was applied to glibc 2.29 or newer.

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.
