Well, I probably should have included this instead. This comes from the
single line added to share/libmpi/Makefile.am

Also, for what it's worth, there is one other patch that's being applied to
deal with the same sort of issue. My fault again for not including it
earlier. Attached as 7.1.2-liblam-use-extra-libs.patch. It takes care of
the following build error that again, only occurs with the noted LDFLAGS.
