Well, if the use of the mmxext flag leads to instructions in
the compiled code which the cpu does not have, then CRASH.

But the SSE instruction sets supersede MMX (and mmxext) and so the
mmxext flag is really unnecessary on Core i7 and many newer processors.
(Ffmpeg may have reasons for still using MMX but I don't know.)
