As mose showed in #261
Clang doesn't find the libs when using arm + musl

That's a good guess:
sandbox:${WORKSPACE} # clang -print-search-dirs
programs: =/opt/x86_64-linux-musl/bin
libraries: =/opt/x86_64-linux-musl/lib/clang/13.0.1:/opt/arm-linux-musleabihf/arm-linux-musleabihf/sys-root/lib/../lib:/opt/arm-linux-musleabihf/arm-linux-musleabihf/sys-root/usr/lib/../lib:/opt/arm-linux-musleabihf/arm-linux-musleabihf/sys-root/lib:/opt/arm-linux-musleabihf/arm-linux-musleabihf/sys-root/usr/libthe list of libdirs is missing /opt/arm-linux-musleabihf/arm-linux-musleabihf/lib, where the gcc toolchain libraries are.
