It is a dependency back to our Python changes that makes our
NumPy changes less palatable from an upstreaming perspective.
Really, we want to know if Python has been built with GCC, and
that is exactly what 'GCC' in sys.version determines.
* Update python2 to 2.7.11
* Update numpy to 1.10.2 (and number the patches).
* New python2 + 3 patch so that sys.version returns
something more similar to normal CPython so that
get_build_architecture in distutils msvccompiler.py
returns the right thing (NumPy uses it so there's
every chance other things will too).
