                      known MACHINE/MACHINE_ARCH values in which either MACHINE

        After significant updates to third-party components in the source tree,
        the ``make cleandir'' operation may be insufficient to clean out old
        files in object directories.  Instead, one may have to manually remove
        the files.  Consult the UPDATING file for notices concerning this.
