Makefile.def (bootstrap stages): Add 'lean' parameter.
2004-08-26 Paolo Bonzini <bonzini@gnu.org>
* Makefile.def (bootstrap stages): Add 'lean' parameter.
* Makefile.tpl (configure-stageN-*, all-stageN-*): Turned into
phony targets; do not generate timestamp files.
(distclean-stageN): Remove references to their timestamp files.
(restageN, touch-stageN): Remove.
(stageN-bubble): Rewritten.
(compare): Support lean bootstraps.
* Makefile.in: Regenerate.
* configure.in: Only warn when bootstrapping but
build != host or build != target. Support lean bootstraps.
* configure: Regenerate.
