[PATCH nolibc 12/19] selftests/nolibc: allow building i386 with multiarch compiler

From: Paul E. McKenney
Date: Thu Oct 12 2023 - 15:33:04 EST


From: Thomas Weißschuh <linux@xxxxxxxxxxxxxx>

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.
