Hmm, I suspect the logic in testsuite/mk/test.mk for determining whether
LLVM is available is flawed. It concludes that LLVM is unavailable if
LLC=llc. I can only assume that the reason for this is that configure
will often find the system's on PATH (in which case LLC=llc) which
likely isn't the LLVM release that we expect.

However, we probably ought to be more careful here.

Could you comment on what LLC is set to in your environment?

Cheers,
