What env flag are you setting, LIBS?  If so, that may not be safe if
configure adds other flags to LIBS (or may do so conditionally)...?

Just curious: this sounds like a symptom of the same reason that OMPI is not
built until after OFED is installed (library paths change between building
and installing).  Is that why you're doing this for mthca and libipathverbs
during the OFED build?
