PR testsuite/12040:

	* lib/future.exp: New file, mostly extracted from ada.exp.
	Rewrote compatibility code to use rename.
	(gdb_find_gfortran): New proc.
	(gdb_default_target_compile): Refresh from dejagnu; plus a pending
	gfortran patch.
	* lib/ada.exp (gdb_find_gnatmake, gdb_default_target_compile):
	Move to future.exp.
	* lib/gdb.exp: Always load future.exp.
