Thomas Petazzoni 6520762932 python: move to Git formatted patches 
Now that the cpython project has a nice Github repository, with tags,
it's much nicer to handle the stack of Python patches with Git. The
python3 package patches had already been converted, but not the python
package patches. Therefore, this commit does the move.

There is no functional change, only reformatting of the patches.

Subject: [PATCH] Fix python-config for cross-builds
Add a backport of http://bugs.python.org/issue16235 so we can use
python-config for cross builds.
This basically replaces the python version of python-config with a
pure-shell version that's already preprocessed when installed and
doesn't depend on the sysconfig import that usually leads to bad
data/results.
