    PR modula2/121709: Failed bootstrap in m2

    This patch is a followup to PR modula2/121629 which uses
    the cpp_include_defaults array to configure the default search path
    entries.  In particular it creates default search paths
    based on LOCAL_INCLUDE_DIR, PREFIX_INCLUDE_DIR, gcc version path
    and NATIVE_SYSTEM_HEADER_DIR.

    gcc/m2/ChangeLog:

            PR modula2/121709
            * gm2-lang.cc (concat_component): New function.
            (find_cpp_entry): Ditto.
            (lookup_cpp_default): Ditto.
            (add_default_include_paths): Rewrite.
            (m2_pathname_root): Remove.

    gcc/ChangeLog:

            PR modula2/121709
            * doc/gm2.texi (Module Search Path): Reflect the new
            search order.
