Any ideas?
Steal the CPU detection code from ATLAS and use that to test to see if the processor we're running on is the same as the processor we compiled for? That seems like a bit much. How about compiling a generic binary (i.e., minimal optimizations)? Is that possible with ATLAS and the other programs?
