* Makefile.tpl (touch-stage[+id+]): New. (restage[+prev+]): Depend on touch-stage[+id+]. * Makefile.tpl (RECURSE_FLAGS_TO_PASS): New. Use it throughout. * Makefile.def: Add profile and feedback bootstrap stages. Remove next field from bootstrap stages. * Makefile.tpl (LN, LN_S): Substitute. (stageN-start, stageN-end): Use double-colon rules, to provide a hook for additional setup commands. (distclean-stageN-gcc, restageN): Create dependencies from [+prev+], not from [+next+]. (stageN-bubble): Add commands for successive stages from [+prev+], using double-colon rules. (all-stageN-gcc): Fix typo. (stagefeedback-start, profiledbootstrap): New. * Makefile.in: Regenerate. * configure.in: Call ACX_PROG_LN. * configure: Regenerate. config/ChangeLog: 2004-06-09 Paolo Bonzini <bonzini@gnu.org> * acx.m4 (ACX_PROG_LN): From gcc, modified to accept a parameter.
