Threaded python on FreeBSD

Currently, the FreeBSD ports make the following change when building
python:

-ifneq (,$(wildcard $(python_libdir)/libpython*$(DLSUFFIX)*))

If that's not in-place, plpython won't build if the python that's
installed is multi-threaded:

I'm turning off threading in my python for now, but ISTM it'd be good to
allow for building plpython from source. (This is python2.5 and FreeBSD 6.1). I
looked around the config files but didn't see a clean way to handle this (and
maybe the issue is actually with autoconf...)
