Svav/make python hub

Adding a new recipe to enabled python on the target. 
The recipe is based on the description from this page: 
http://www.trevorbowen.com/2013/10/07/cross-compiling-python-2-7-5-for-embedded-linux/ 
 And I have used the patch he refers as the basis, but it has been modified slightly. 

I have tested the build on a RaspberryPI running: 
python /usr/lib/python-2.7/test/test___all__.py
