[PATCH v2 0/3] tools/nolibc: add support for SuperH

Add support for SuperH/"sh" to nolibc.
Only sh4 is tested for now.

This is only tested on QEMU so far.
Additional testing would be very welcome.
Test instructions:
$ cd tools/testings/selftests/nolibc/
$ make -f Makefile.nolibc ARCH=sh CROSS_COMPILE=sh4-linux- nolibc-test
$ file nolibc-test
nolibc-test: ELF 32-bit LSB executable, Renesas SH, version 1 (SYSV), statically linked, not stripped
$ ./nolibc-test
