It seems that the right place to put this is BE_DLLLIBS, which is a
macro that probably didn't exist when the AIX support was last looked
at. But both Windows and Darwin ports use it now, so we may as well
bring AIX up to speed. Would you try the attached patch and see if it
gets rid of the warnings? Also check that regression tests and contrib
build/regression tests still work.
