* configure.in: Check that the pthdebug library is recent enough

       before enabling thread support on native AiX.
       * configure: Regenerate.

       from the list of object files as it is now appended by configure
       if thread support is enabled.
       (NAT_CLIBS): Removed as -lpthdebug is also appended by configure
