2004-08-06 Paolo Bonzini <bonzini@gnu.org>

	* Makefile.def (bfd, opcodes, gcc, zlib): Mark as bootstrap module.
	(bison, byacc, flex, texinfo): Do not mark as bootstrap module.
	(Dependencies): New section.
	* Makefile.tpl (Dependencies): Generate from Makefile.def.
	(configure-target-[+module+]): Depend on maybe-all-gcc
	(all-prebootstrap): New name of all-bootstrap.  Changed throughout.
	(toplevel profiledbootstrap): Fix dependencies.
	* Makefile.in: Regenerate.
