Subject: [PATCH 1/4] selftests/nolibc: allow building i386 with multiarch compiler
Date: Thu, 14 Sep 2023 18:01:17 +0200 [thread overview]
Message-ID: <20230914-nolibc-syscall-nr-v1-1-e50df410da11@weissschuh.net> (raw)
In-Reply-To: <20230914-nolibc-syscall-nr-v1-0-e50df410da11@weissschuh.net>
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.
