Interesting idea.

This change does seem to have helped for arm64, but the jury's still out
on mips64el.  However, I see new failures on amd64 and s390x, and builds
for many architectures (albeit all non-release ones) can no longer even
start because clang is unavailable there.  As such, I'd recommend
building with (and build-depending on) clang only on those architectures
on which GCC builds hit errors.

On the Mac front, Clang has indeed been the only compiler Apple's
official Development Tools package supports for years (briefly preceded
by LLVM GCC), but GCC does still support the platform and is available
through third-party package managers such as Fink.

At any rate, thanks for looking into the errors!
