It's been a while since RISC-V support was added to CT-NG in 2017.
Since then RISC-V support was integrated in all the key toolchain
components upstream and now are proven to be in a very good state.
Thus it makes no sense to keep this architecture "hidden" in
experimental options, so we promote RISC-V architecture in CT-NG.

Musl was marked experimental in commit 08d91d41 ("musl: config is broken
for !EXPERIMENTAL"). Most of the reasoning for that change no longer
applies and as it's been about 8 years it's time to let musl loose on
the world. Drop the `depends on EXPERIMENTAL` and update the sample
configs for aarch64 and x86_64.
For powerpc64 the ABI needs to be elfv2. Enforce this via the powerpc
config. Add a sample configuration for powerpc-unknown-linux-musl.

This patch removes any dependency to the Oracle UEK Linux sources since
it can be easily replaced by a standard kernel explicitly pointing to
the exact kernel version, as the toolchain building only requires the
kernel headers.

Some m68k variants do have a MMU so the architecture can set
ARCH_USE_MMU. That means we can have a m68k-unknown-linux-gnu
configuration and that m68k-unknown-uclinux-uclibc needs to select
LIBC_UCLIBC_NG since it's no longer the default.

moxie-unknown-moxiebox has problems building with newlib 4.3
ld: /lib/libc.a(libc_a-closer.o): in function `_close_r':
newlib/libc/reent/closer.c:47: undefined reference to `_close'
There are some Makefile changes in newlib 4.3 and it's likely previously
this config was picking up `_close` from libsim.a. For now just pin the
newlib version back to 4.2 in the moxie-unknown-moxiebox config.

CC_CC_GCC_ENABLE_DEFAULT_PIE=n is invalid Kconfig syntax for an option
that was intentionally disabled the saved config would be
'# CC_CC_GCC_ENABLE_DEFAULT_PIE is not set'
but the DEFAULT_PIE option isn't selectable for RISCV && BARE_METAL so
the correct thing to do is just remove the config.
This also picks up a change regenerating the saved sample due to changes
in the Kconfig ordering.

--enable-e500_double was valid but strange (the correct form is
--enable-e500-double). -Wa,-me500x2 was also misleading, it is
equivalent to Wa,-me500. --enable-e500x2 --with-e500x2 did nothing as
they aren't used by the binutils configure script. Finally passing
-mfloat-gprs=double in CFLAGS is unnecessary because this is the default
when using -mcpu=8548. Correct these in the sample config.

GDB10+, you need GCC9+.

2.6.32.71, respectively. Interestingly, 2.12.1 was marked as being used

and glibc 2.12 is going to be marked obsolete, and retired soon.
