* ltconfig: Define file_list_spec. Pass file_list_spec and

        with_gnu_ld to libtool.
        * ltcf-c.sh (aix[45]): Define file_list_spec.
        * ltcf-cxx.sh (aix[45]): Same.
        * ltcf-gcj.sh (aix[45]): Same.
        * ltmain.sh: If command exceeds max_cmd_len and file_list_spec
        exists, write list of input files to temporary file.
