Makefile.in (libgcc.ready): Lose.

        * Makefile.in (libgcc.ready): Lose.
        (libgcc.mk): Just use mv, not move-if-change.
        (LIBGCC_DEPS): New macro.
        (libgcc.a): Use it.
        (stmp-multilib): Likewise.
        * mklibgcc.in (stmp-dirs): New target.  Make everything depend on
        it rather than the directories themselves.
        (LIB2ADD): Depend on the list file rather than 'force'.
