Yes, it did, because Howard's commit was wrong.

I'm not sure what the exact problem was he was fixing (the commit message 
wasn't very specific), but the shell variable names were already correct -- 
they are to indicate whether a specific provider (usnic, in this case) can be 
built; not the libfabric core.

However, there was a problem where provider libs were being unconditionally 
added; this *may* have been Howard's problem...?

I just pushed a fix for that: 
https://github.com/open-mpi/ompi/commit/c40fd09d2a0575e493137158644fd2b610a48aca

Howard's here at the Forum with me; I'll consult with him in person later this 
morning.
