Log:
        PR driver/20425
        * gcc.c (for_each_path): New function.
        (add_to_obstack, file_at_path): New functions.
        (struct file_at_path_info, struct add_to_obstack_info): New.
        (build_search_list): Rewrite using for_each_path.  Constify struct
        path_prefix pointer.  Add do_multi param.  Adjust all callers.
        (find_a_file): Similarly, but just change existing param to bool.
        (putenv_from_prefixes): Add do_multi param, make "paths" const.
        (do_spec_path): Delete.
        (struct spec_path_info): New.
        (spec_path): New function.
        (do_spec_1): Use for_each_path for %D and %I.
        (find_file): Adjust for find_a_file changes.
        (main): Search multilibs for specs.  Print multilib lib path for
        -print-search-dirs.  Likewise add multilibs to LIBRARY_PATH_ENV.
        (read_specs): Search multilibs for %include and %include_noerr.
        (is_directory): Remove second string param.  Change last param
        to a bool.  Don't use concat.  Remove SMALL_ARG_MAX test, always
        check path is a dir.  Update all callers.
        * doc/hostconfig.texi (SMALL_ARG_MAX): Remove mention.
        * system.h (SMALL_ARG_MAX): Poison.
        * config.gcc: Don't define SMALL_ARG_MAX.
        * config.host: Likewise.
        * config.build: Likewise.
