choose-temp.c (make_temp_file): Accept new argument for the file suffix to use.

        * choose-temp.c (make_temp_file): Accept new argument for the
        file suffix to use.  Allocate space for it and add it to the
        template.
        * mkstemp.c (mkstemps): Renamed from mkstemp.  Accept new argument
        for the length of the suffix.  Update template struture checks
        to handle optinal suffix.
        * collect2.c (make_temp_file): Update prototype.
        (main): Put proper suffixes on temporary files.
        * gcc.c (make_temp_file): Update prototype.
        (do_spec_1): Put proper suffixes on temporary files.
Should fix irix build problems.
