bsd.python.mk patch for review

[Antoine Brodin]

Hi there,

Currently default python versions are inconsistent:
- python 3.3 is the default python3 version
- python 3.4 is preferred over python 3.3 when a port needs a python
version in a specific range

The patch below should address this,  please review/test.

Cheers,

Antoine
