        * configure.tgt: Configure gdbserver only for known working
        targets.  Set ${build_gdbserver} instead of modifying ${configdirs}.
        * configure.in: Check ${build_gdbserver}.  Put gdbserver/ into
        SUBDIRS if it is configured.  Update comment for ${nativefile}.
        * configure: Regenerated.
