Add nolibc support for m68k. Should be helpful for nommu where
linking libc can bloat even hello world to the point where you get
an OOM just trying to load it.

While nolibc does support ARM Thumb instructions,
that support was not tested specifically.
Add a new test configuration for it.

32-bit s390 is very close to the existing 64-bit implementation.
Some special handling is necessary as there is neither LLVM nor
QEMU support. Also the kernel itself can not build natively for 32-bit
s390, so instead the test program is executed with a 64-bit kernel.

Support for 32-bit s390 is about to be added.
As "s39032" would look horrible, use the another naming scheme.
32-bit s390 is "s390" and 64-bit s390 is "s390x",
similar to how it is handled in various toolchain components.

The list is getting overly long and any modifications introduce a lot of
noise and are prone to conflicts. Split the string into a bash array
and break that into multiple lines.

Avoid using a stale test kernel configuration by always synchronizing
it to the current source tree.
kbuild is smart enough to avoid spurious rebuilds.
Shuffle the code around a bit to keep all the commands with side-effects
together.

nolibc already supports riscv32. Wire it up in the testsuite.

riscv32 support is about the be added. To keep the naming clear and
consistent with other architectures rename riscv to riscv64, as that is
what it actually represents.

The script tries to resolve the path to the current toolchain using
realpath, which fails in case it's not installed, and since it's run
under -e, it doesn't have the opportunity to display a help message.
Let's detect the absence of the required toolchain before running that
command and provide a friendlier message when this happens.

The nolibc tests can now be properly built with LLVM.
Expose this through run-tests.sh.

If the user specified their own CFLAGS_EXTRA these should not be
overwritten by `-e`.

run-tests.sh hides the output from the compiler unless the compilation
fails. To recognize newly introduced warnings use -Werror by default.
Also add a switch to disable -Werror in case the warnings are expected.

The script can run the testsuite for multiple architectures and provides
an overall test report.
Furthermore it can automatically download crosstools from
mirrors.kernel.org if requested by the user.
Example execution:
$ ./run-tests.sh
