* Makefile.in (STAGESTUFF): Add libgcc libgcc.mk.

        (libgcc1.null, libgcc1.cross, libgcc1.a): Remove targets.
        (libgcc1-asm.a, libgcc1.S, libgcc2.a): Remove targets.
        (mklibgcc, libgcc.mk): New targets.
        (libgcc.a): Use libgcc.mk.
        (stmp-multilib): Likewise.
        (stmp-multilib-sub): Remove.
        (mostlyclean): Don't delete libgcc2 temp files.
        * configure.in (AC_PROG_CC_C_O): Add.
        (NO_MINUS_C_MINUS_O): Substitute it.
        (all_outputs): Add mklibgcc.
        * mklibgcc.in: New file.
