Re: [toplevel PATCH] add some new-bootstrap targets, and keep directory structure correct

References: <4088D312.2030807@gnu.org>

Hi, this patch is the result of trying to do some work with new-bootstrap. I found that it was a bit inconvenient when builds failed, because then you had directories with unexpected names around and often I did not remember which directories was for which stage. I also sorely missed restage1 and friends.

I missed that "compare" is also a stampfile. This fixes it.

	* Makefile.tpl (all-stage1-gcc, all-stage2-gcc, all-stage3-gcc):
	Always relocate gcc and prev-gcc to the original names, even
	if the build fails.
	(new-cleanstrap, new-restage1, new-restage2, new-restage3):
	New targets.
