Makefile.in (FPBIT_FUNCS, [...]): Define.

        * Makefile.in (FPBIT_FUNCS, DPBIT_FUNCS): Define.
        (libgcc2.a): Depend on $(DPBIT) and $(FPBIT).  Add rules to
        generate more fine grained floating point emulation libraries.
        * config/fp-bit.c: Add protecting #ifdef to all functions so
        that they can be compiled separately.  If !FINE_GRAINED_LIBRARIES,
        then compile all suitable functions.
        (pack_d, unpack_d, fpcmp_parts): Add declarations, define with two
        underscores to avoid namespace pollution.
        * t-mn10200 (LIB2FUNCS_EXTRA): Remove fp-bit.c
        (FPBIT): Define.
        * t-mn10300 (LIB2FUNCS_EXTRA): Remove fp-bit.c and dp-bit.c
        (FPBIT): Define.
        (DPBIT): Define.
