And this is a patch to workaround the cloog parts.  We cannot
use $(HOST_GMPLIBS) because it includes -lmpc and -lmpfr (which
we do not depend on), and $(HOST_ISLLIBS) does not exist.

Those are cleanup opportunities.

Tested with in-tree gmp and out-of-tree gmp and committed.

	* Makefile.def (cloog): Pass $(HOST_GMPINC) and $(HOST_ISLINC)
	as CPPFLAGS, pass path to built gmp as LDFLAGS, always use
	--with-gmp=system.
	* Makefile.in: Regenerated.
	* configure: Likewise.
