I tried this, this does not work (it actually emulates SSE). I went
further, and managed to disable SSE support in qemu...
But again, what's the point: it takes ages to compile (qemu without
the hardware accelerator is slow, like ten times slower), and you will
end up with a really bad atlas, since atlas optimizaton is entirely
based on runtime timers, which do not make sense anymore.
I mean, really, what's the point of doing all this compared to using
blas/lapack from netlib ? In practice, is it really slower ? For what
? I know I don't care so much, and I am a heavy user of numpy.
