lang/python26 -- without threads

[Christopher Sean Hilton]

The port lang/python26 can be built with or without threads. If built without the package will not install the file:

     %%PYTHON_LIBDIR%%/lib-dynload/_multiprocessing.so

This causes error building a package from the port as well as maintaining it afterwards. 

I don't know the exact magic-foo to fix this kind of problem in the ports collection but I can look it up and find it. I'm just under the gun on another project right now. When I can revisit this I'll come up with a solution for the problem, put in a proper PR and a patch to fix the Makefile and or pkg-plist.
