Patch for the math/py-matplotlib port Makefile.
The recent revision 426883 restricted matplotlib to Python 2.7 because it fails with Python 3.
However, this is *only true* in the default configuration.
When the gtk and gtkagg backends are disabled and the tkagg backend is enabled, matplotlib builds, installs and works fine with Python 3 (tested with Python 3.5) if I change `python:2.7` back to `python` in USES.
The attached patch adds the correct python to USES after the options are processed. But the build fails for some reason that I do not understand. During `make PYTHON_VERSION=python3.5 build` it says that matplotlib depends on `tkinter>0`, which it says it cannot find even though py35-tkinter-3.5.2_6 is already installed.
Probably this needs to done differently, but I don't see how.
