SSE2 is guaranteed feature of the AMD64 (a.k.a. x86_64) architecture,
and it's a big help to use it, even where SIMD vector operations are not
needed.  It would be a bad idea to disable it outright.

I think we should hold out for a better solution than simply disabling
SSE2 support on all systems.

      Thanks,
        Mark
