Enabling the native controller support

[CurlyMo]

I think there are some things crossing each other:
1) Our wayland + XBMC experimentation for which we need an SDL
2) Our current (default RPi) XBMC implementation which uses the video driver directly

If you are trying to achieve the first one, then you will probably run into a lot of difficulties. I still would like to test the first build here. If you are trying to add an SDL to the second option then you're indeed doing some wierd things because the whole point of a fluent XBMC for the RPi at this moment is it is built so it can run without the X display driver and SDL.
