Fix bug 650: use general macros $(LIBLAM_LA) and $(LIBMPI_LA) to link

to relative libraries -- need these to be variables because configure may
decide to compile them both as libmpi (and therefore there is no libmpi).
Correct usage is to use *ONE* of these two macros when adding it to LIBADD
lines in Makefile.am's -- if you use $(LIBMPI_LA), it will automatically
include liblam if it needs it.
