OK fine.  Currently we have 3.6 and 3.5, so we’d add 3.8 on top of it,
right?  And the ‘llvm’, ‘clang’ etc. bindings would still point to 3.6?
Does it even make sense to have unversioned bindings?

The patch you posted earlier adds a number of configure flags, different
from those currently used in ‘llvm’, and in particular:

> +                           "-DLLVM_INCLUDE_TESTS=OFF" ;; clang target units cannot be built (invalid test targets inherited from llvm result in build failure)

IIUC, this has the effect of disabling tests, which is something we
avoid unless there’s a good reason.  I don’t understand the comment,
what’s happening?

Could you remove as many of the configure flags as needed, and add a
comment for those that need to remain?

Also, as a bonus, could you add a conforming commit log?  :-)

Thanks in advance!
