- Added some $(LDFLAGS) in Makefile.in's so executables will find libgmp.

- Wrote a check to see if libgmp can be used. - Added libtool interface versioning (-version-info) for the library. - Added libtool inter-library dependency for -lgmp. (Libtool should care if this works on the current platform.)
