[PATCH v2] configure: remove dependencies on gmp and mpfr when gdb is disabled

["Clément Chigot" <chigot@adacore.com>]

Since 991180627851801f1999d1ebbc0e569a17e47c74, the configure checks
about GMP and MPFR for gdb builds have been moved to the toplevel
configure.
However, it doesn't take into account the --disable-gdb option. Meaning
that a build without gdb will require these libraries even if not
needed.

ChangeLog:

	* configure.ac: Skip GMP and MPFR when --disable-gdb is
	provided.
	* configure: Regenerate.
