Unable to link lib_swig_python

Hi Sigfred. r18156 (r17910 on trunk) is absolutely necessary for
linking libsvn_swig_py on Solaris 10 with Python 2.2.3 (and GCC), and
did not cause problems on any other platforms it was tested on. Can
you give the following patch a try on OpenBSD?

Also, if there's any way you'd be able to test this patch on OpenBSD
with an older version of Python (e.g. one which doesn't actually have
a libpython2.X.so, only libpython2.2.a like the Solaris 10 environment
which necessitated r18156), that would be fantastic.

Thanks, Dan
