Subject:        * configure.in: Check that the pthdebug library is recent
 enough        before enabling thread support on native AiX.        *
 configure: Regenerate.

       * config/powerpc/aix432.mh (NATDEPFILES): Remove aix-thread.o
       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
       if thread support is enabled.
