Generally these don't give dramatic speed increases, but they _DO_
generate bug reports from people on incompatible CPUs.

Plus it's a pain to build and distribute multiple binary versions.

There is definitely something inefficient in the spearhead server as
opposed to the original MOHAA one...but this is a logic issue as opposed
to a CPU-specific bottleneck.
