Never mind; the `-tp PROCESSOR' gets reordered badly by libtool anyway,
so only `-tp=PROCESSOR' is feasible.  Updated patch below.  OTOH,
another workaround should be to pass -Wc,-tp=k8-32 to `libtool
--mode=link'.

Cheers,
Ralf

    Allow through -tp=* at link time, for pgcc.

    pgcc uses `-tp=PROCESSOR' for target processor selection; allow
    the flag through at link time.
    * THANKS: Update.
