Easy, you cross compile from Go on a different architecture. Go apparently has a good cross compilation story, though I don't have experience with it; honestly IMO the whole perception that cross compiling is an unusual or difficult thing comes from poorly designed Unix build systems. Though I suppose this would make a fully automated bootstrapping system a bit messier. (Do the first build in an emulator?)
