Subject: [PATCH v2 1/4] selftests/nolibc: allow building i386 with
 multiarch compiler

When building with a multiarch-capable compiler, like those provided by
common distributions the -m32 argument is required to build 32bit code.

Wrap it in cc-option in case the compiler is not multiarch-capable.
