e58fd0a23e musl: Mark not EXPERIMENTAL
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.

4442dc87dd config: Detect rsync presence at config time
Linux kernel versions newer than 5.3 require rsync in order to export
the UAPI headers. Commit f441a6bf ("linux: Add dependency on rsync for
Linux >= 5.3") attempted to address this with a check that runs when
crosstool-ng is built. That had the downside that if crosstool-ng was
built and packaged on a machine that had rsync then run on a machine
that didn't then the build would fail due to the missing rsync.
Conversely if the first machine didn't have rsync installed when
crosstool-ng was built then we would not offer newer kernel versions.

We can address this by checking for rsync when the toolchain
configuration is updated using some functionality in the newer Kconfig
that we've updated to previously.

daf19e1761 gdb: Use correct arguments for static linking
As of version 13.x GDB uses libtool for linking instead of g++ these
take different arguments for static linking.  Commit 6146b5a6 ("use
-all-static when building a static gdb") attempted to deal with this but
had the effect of causing older GDB versions to fail to build
statically. Add a new internal flag GDB_CC_LD_LIBTOOL and use this to
decide whether to pass `-static` or `-all-static`.

cdae8d0559 Enable support for building libgccjit
libgccjit is still under development and, despite its name, may also be used for
ahead-of-time compilation.

Documentation can be found on the gcc website:
https://gcc.gnu.org/onlinedocs/jit/internals/index.html
https://gcc.gnu.org/wiki/JIT

With this change it's possible to enable the building of the libgccjit. It's
enabled as a language (with --enable-languages=jit) even if not a language
frontend at all.

The main changes are related to the requirement of having everything host side
built as Position Independent Code (PIC) with --enable-host-shared. GCC has the
needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when
built "in-tree", which is not the case with crosstool-ng (see
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0)
