Add GCC 10.4.0 and regenerate the ct-ng patches. The
powerpc-Fix-asm-machine-directive-for-some-CPUs patch is dropped as the
change was applied upstream (and subsequently refactored).
Closes#1777

This reverts commit 1b6ad7cd48. As it
turns out libsanitizer isn't supported on mips64 with GCC11 or older
(there is support in GCC12). The bug is actually the fact that ct-ng
allows configuring libsanitizer for architectures that don't support it.

Extend the fix from commit 6b465e15 ("Remove m1 from multilibs for GCC11
on SH arch.") to cover GCC 12 and future releases.
Remove the patch that was added to solve the same problem.

For some reason GCC 12 ends up hitting the _MIPS_SIM_NABI32 case for
Linux's arch/mips/include/uapi/asm/stat.h when building libsanitizer.
This is basically the opposite of the problem from
commit 1b6ad7cd ("gcc: Bring in fix for libsanitizer on mips64").
Dropping the patch resolves the issue for GCC 12.

Add GCC 12.1 https://gcc.gnu.org/gcc-12/
The following patches from GCC 11.3.0 are no longer needed:
- 0005-arc-Update-ZOL-pattern.patch
- 0006-arc-Update-u-maddhisi4-patterns.patch
- 0007-arc-Fix-maddhisi-patterns.patch
- 0008-Darwin-aarch64-Initial-support-for-the-self-host-dri.patch
- 0009-libstdc-Check-for-TLS-support-on-mingw-cross-compile.patch
One new patch is needed to avoid issues building sh-unknown-elf:
- 0006-sh-Avoid-mb-m1-multilib-combination.patch
It is also necessary to build all-build-libcpp. This target exists as
far back as GCC 6 so has been done unconditionally.

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).

... and the code dependent on them, after the latest wave of obsolete
package removals. This concludes the glorious history of the original
uClibc (non-NG) with lots of kludges removed.
There was a choice here, whether to call the resulting libc "uClibc" or
"uClibc-ng". I opted in favor of giving uClibc-ng the recognition it
deserves, although it had some ripple effect in the ct-ng code.

GCC 4.8 and its prerequisites have been removed by 04dce680, 41d4583a
and e4221734; as a result, 4.8-based version of gcc-oracle became
unbuildable (no valid versions for the prerequisites).
Update the samples to use 4.9.4; which however fails to build on a modern
host GCC. Build fix backported to gcc-4.9 and gcc-5 versions.

With this we may finally build Windows and "native" toolchains
if host tools are also GCC11 based. For example:
1. You build cross toolchain with all the recent components by CT-NG
2. You build cross-canadian toolchain for Windows or ARC, ARMm whatever board
See upstream bug report [1] for more details.
Basically when we do cross-canadian build with
use of the same GCC11 as a "host" compiler we're seeing
an error like that:
------------------->8-------------------
mingw-w64-cross/gcc/x86_64-w64-mingw32/libstdc++-v3/include/fenv.h:58:11: error: 'fenv_t' has not been declared in '::'
58 | using ::fenv_t;
------------------->8-------------------
This is a solution proposed by Yujie Yang in [2]
Note, though it's not the final fix merged upstream, that's just
an attempt to fix this by casual GCC users. There's a hope it
will be fixed anyways a bit later, maybe by the time of GCC 11.3...

Some of the installed libstdc++ header files use '#include_next' to
work around toolchain oddities that might cause loops in the
compiler. However, these also cause mistakes in locating header files
when there are multiple C libraries installed as '#include_next' often
ends up finding default C library header files.
It doesn't seem like this patch could be accepted upstream; there's a
long discussion about the use of include_next in these headers which I
cannot fully understand.
