Sorry, a few more fires have popped up in the meantime.  Regardless of
changes to the compiler, we still support many versions of clang for
the kernel, so we'd need some workaround in the tests regardless.  I
saw there was already one for s390 + clang, but from this report we
will need another. Feel free to use that link above in comments in the
tests; we will clean those up once I have a better grasp on what's
going on with the compiler here.
