on Darwin, it works for later systems without multilibs, but fails to build multilibs.

—— so….

With the patch below bootstrap suceeded on x86_64-darwin17 and produced a correct
architecture multilib.  Of course, there is no way to test this at the moment - I’d suggest
that the next step might be something small in functionality that can allow at least one
test to be wired up.

^^^ this is “lightly tested” of course, as I cycle through other versions of the OS will see
how it pans out.

Do you want me to make a PR with this change against upstream?
