My concern is that they might not build on some architectures for which I 
don't have a cross-compiler. For instance not all architecture define ioread32 
and iowrite32, which some drivers might rely on. What about depending on 
SUPERH || ARM || COMPILE_TEST to start with, in order not to push compilation 
breakages to mainline ?
