2005-12-14 Paolo Bonzini <bonzini@gnu.org>

	* configure.in: Flip the top-level bootstrap switch.
	* configure: Regenerate.

	Merge from gcc:

	2005-12-14  Daniel Jacobowitz  <dan@codesourcery.com>

        * Makefile.tpl: Throughout the file, use : $(MAKE) along with
        $(stage) and $(unstage).
        (EXTRA_TARGET_FLAGS): Correct double-quoting.
        (all): Remove stray semicolon.
        (local-distclean): Don't handle multilib.tmp and multilib.out.
        (install.all): Set $s for consistency.
        (configure-[+prefix+][+module+]): Instead of [+deps+], handle
        check_multilibs setting.  Always make the install directory.
        (configure-stage[+id+]-[+prefix+][+module+]): Likewise.
        Correct @if/@endif.
        (all-stage[+id+]-[+prefix+][+module+]): Correct @if/@endif.
        ($(TARGET_SUBDIR)/[+module+]/multilib.out): Remove.
        (stage[+id+]-start, stage[+id+]-end): Stage $(TARGET_SUBDIR).
        (multilib.out): Remove.
        * Makefile.in: Regenerated.
