Currently, distclean does not remove the libcc1, gnattools, and gotools
directories, and not the stage_final file either.  Fix that.


	PR bootstrap/70173
	* Makefile.tpl (local-distclean): Delete the libcc1, gnattools,
	and gotools directories.  Delete the stage_final file.
	* Makefile.in: Regenerate.
