perform gmp/unistring compile checks with AC_LIB_HAVE_LINKFLAGS

Browse source 
* configure.ac: Rework gmp and unistring checks to use
  AC_LIB_HAVE_LINKFLAGS, so that the compilation checks run with the
  right -L/-l flags.

* libguile/Makefile.am (libguile_la_LIBADD): Adapt to need to add
  $(LIBGMP) and $(LIBUNISTRING) here.

Hopefully this solves
