Thanks for the bug report. A workaround should be to
./configure CC="pgcc -tp=k8-32"
and the following patch should fix the issue. Can you try both?
Thanks,
Ralf
Allow through -tp and -tp=* at link time, for pgcc.
* libltdl/config/ltmain.m4sh (func_mode_link): Portlant Group
pgcc uses `-tp PROCESSOR' or `-tp=PROCESSOR' for target
processor selection; allow the flag through at link time.
* THANKS: Update.
