Workaround clang+musl build failure
The current configure code detects musl and sets an appropriate suffix
correctly but afterwards verifies that the detection result matches
whatever --print-multiarch prints. Unfortunately, the current Clang
releases incorrectly report linux-gnu on musl, causing the safety check
to fail. Until upstreams sort that out, just nuke the multiarch check
on musl target.
