    Fixing make distcheck issue
    
     * This patch fixes bug #738142 which describes
       and issue that prevents make distcheck from being
       successfully run if make has not been run first.
     * The problem is that make distcheck requires some
       generated files to be present that are only generated
       by make. The solution was to add $(_HELP_LC_FILES) as
       a dependency to distdir-help-files so that these
       files are always generated when make distcheck is run.
