I thought we were moving away from makefile fragments?  Maybe that was
just in the gcc tree.  Here's the alternate implementation.

	* configure.in:  Handle spu makefile frag.
	* configure: Regenerate.
	* Makefile.in (MAINT): Define
	(MAINTAINER_MODE_FALSE, MAINTAINER_MODE_TRUE): Define.
	* config/mt-spu: New file.
