I could find a million threads in the forums supporting what Ciaran is
saying here. We have been told over and over and over until my head
feels bashed in that MMX/SSE, etc... are NOT TO BE PUT IN CFLAGS!! THAT
IS WHAT USE FLAGS ARE FOR!!!!
Every developer who has ever commented on one of these threads has
always agreed with that. Put it in USE not CLFAGS.
To change this behavior now after all this time would be crazy IMHO.
