        PR bootstrap/24252

        * Makefile.def (flags_to_pass): Add STAGE1_CFLAGS and STAGE1_LANGUAGES.
        * Makefile.tpl (OBJDUMP): New.
        (EXTRA_HOST_FLAGS): Add it.
        (EXTRA_GCC_FLAGS): Remove flags already specified in flags_to_pass.

        * Makefile.tpl (stage[+id+]-start, stage[+id+]-end): Do not try
        to use symbolic links between directories.  Avoid race conditions
        or make them harmless.
        * configure.in: Do not try to use symbolic links between directories.

        * Makefile.def (LEAN): Pass.
        * Makefile.tpl (LEAN): Define.
        (stage[+id+]-start): Accept that the previous directory does not
        exist, if the bootstrap is lean.
        (stage[+id+]-bubble): Invoke lean bootstrap commands after
        stage[+id+]-start.  Use a makefile variable and an `if' instead of a
        configure substitution.
        ([+compare-target+]): Likewise.
        ([+bootstrap-target+]-lean): New.
        * configure.in: Remove lean bootstrap support from here.

        * Makefile.in: Regenerate.
        * configure: Regenerate.

	2006-01-02  Andreas Schwab  <schwab@suse.de>

        * configure.in: When reconfiguring remove Makefile in
        all stage directories.
        * configure: Regenerate.
