Like the KARCH added for tools/testing/selftests/nolibc/Makefile, adds
KARCH for tools/include/nolibc/Makefile too, at the same time, adds
NARCH for the ARCH supported by nolibc (arch-<NARCH>.h).

It allows users to customize both kernel and nolibc specific ARCH
variables for different architectures and their variants easily.
