66a4f9bb1e tools/nolibc: Add m68k support
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.

cb839e0cc8 selftests/nolibc: add armthumb configuration
While nolibc does support ARM Thumb instructions,
that support was not tested specifically.

Add a new test configuration for it.

9c812b01f1 tools/nolibc: add support for 32-bit s390
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.

3d1e67c615 selftests/nolibc: rename s390 to s390x
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.

16681bea9a selftests/nolibc: split up architecture list in run-tests.sh
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.

c1f4a7a840 selftests/nolibc: always keep test kernel configuration up to date
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.

4b92b79c56 selftests/nolibc: run-tests.sh: detect missing toolchain
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.

fails. To recognize newly introduced warnings use -Werror by default.

Also add a switch to disable -Werror in case the warnings are expected.
