Nolibc supports the x32 ABI on x86.
Add a testcase to make sure the support stays functional.
QEMU user does not have support for x32, so skip the test there.

The logic would not catch if the test process crashes and would
incorrectly report a "success" state. Fix this by looking for the final
"Total number of errors:" message and printing "failure" if it was not
seen.

tools/scripts/Makefile.include now has the same override,
removing the need for the one in the nolibc Makefile.
Drop the superfluous custom override.

Add support for SuperH/"sh" to nolibc.
Only sh4 is tested for now.
The startup code is special:
__nolibc_entrypoint_epilogue() calls __builtin_unreachable() which emits
a call to abort(). To make this work a function prologue is generated to
set up a GOT pointer which corrupts "sp".
__builtin_unreachable() is necessary for __attribute__((noreturn)).
Also depending on compiler flags (for example -fPIC) even more prologue
is generated.
Work around this by defining a nested function in asm.

For the test implementation of the SuperH architecture a second serial
serial port needs to be used. Unfortunately the currently used 'stdio'
driver does not support multiple serial ports at the same time.
Switch to the 'file' driver which does support multiple ports and is
sufficient for the nolibc-test usecase.

The variable block got disordered at some point.
Use the correct ordering.

Add support for the MIPS 64bit N64 and ILP32 N32 ABIs.
In addition to different byte orders and ABIs there are also different
releases of the MIPS architecture. To avoid blowing up the test matrix,
only add a subset of all possible test combinations.

The nolibc tests are not real kselftests, they work differently and
provide a different interface. Users trying to use them like real
selftests may be confused and the tests are not executed by CI systems.
To make space for an integration with the kselftest framework, move the
custom tests out of the way.
The custom tests are still useful to keep as they provide functionality
not provided by kselftests.
