Libtool is really dumb.  At configure time, it looks at $CC and tries to
find out whether it knows this compiler.  If this is a Linux of some
sort (which I guess it is) and the Portland compiler, then try
  ./configure CC=pgcc

because libtool should recognize pgcc better than cc.  If after that,
  ./libtool --config | grep "^wl"

still shows empty, then you can still try fixing that by editing
libtool manually,
  sed --in-place 's|^wl=.*|wl="-Wl,"|' ./libtool

If this is not the Portland compiler on Linux, then Libtool first needs
to be ported to that combination.

Hope that helps.

Cheers,
Ralf
