Porting the Dolphin Emulator to the modern OpenPOWER systems

cross post from https://forums.raptorcs.com/index.php/topic,593.0.html

As I am using my Talos II mostly for gaming currently, I decided to port the Dolphin Emulator. From my work on Libre-SOC I have a good understanding of the Power ISA. At the same time I will also continue working on OpenPOWER Microwatt and jit compilers. Hopefully I will be able to reuse some of the code that I plan to write for a later Box86 / Box64. As a first game for testing I have selected SuperTux Wii (or the GameCube port).
