Subject: [PATCH v2 12/13] tools/nolibc: add __nolibc_static_assert()

Add a wrapper for _Static_assert() to use within nolibc.
While _Static_assert() itself was only standardized in C11,
in GCC and clang dialects it is also available in older standards.

If it turns out that _Static_assert can't be used in some contexts,
this wrapper can be adapted.
