re PR bootstrap/42424 (in-tree GMP/MPFR/MPC bootstrap fails)

	PR bootstrap/42424
	* configure.ac: Include libtool m4 files.
        (_LT_CHECK_OBJDIR): Call it.
	(extra_mpc_mpfr_configure_flags, extra_mpc_gmp_configure_flags,
	gmplibs, ppllibs, clooglibs): Use $lt_cv_objdir.
	
	* configure: Regenerate.
