	* Makefile.tpl (sorry): Remove.
	(clean-stage[+id+], clean-stage[+id+]-module): New targets.
	(cleanstrap targets): Depend on distclean, not distclean-stage1.
	(do-clean): Clean per-stage directories too.
	(do-distclean): Run distclean-stage1 too.
	(.NOTPARALLEL): Enable during toplevel bootstrap.
	(stage[+id+]-bubble): Enable parallel execution during
	the recursive invocation.
	* Makefile.in: Regenerate.

	Sync from gcc (moving the Makefile.in change to Makefile.tpl):

	2004-08-31  Robert Bowdidge <bowdidge@apple.com>

	* Makefile.in: Move BOOT_CFLAGS above host makefile fragment include.
	* configure.in: add test for powerpc-*-darwin* to specify makefile frag
	* configure: regenerate
	* config/mh-ppc-darwin: create file, override BOOT_CFLAGS for
        -mdynamic-no-pic
