Makes sense. No SSE on ia64.

The culprit is very likely in src/SConscript.env in line 1327.

The bitwidth=='64' check is no valid indication for turning on SSE and
the lot.

I'd add a "and (machine == 'AMD64' or machine == 'EM64T')" to the
bitwidth condition.

Or even reverse the complete logic and require explicit setting of the
optimize flag to turn on ALLOW_X86_OPTIMIZATIONS.
