The SSE2 detection and enabling could potentially cause
problems for binary distributions of Python in situations
where the build machine has SSE2 but the target machine
does not.
Therefore, don't enable SSE2 instructions automatically on x86.

(This minor issue has existed in 2.x for a long time.) -- On x86, SSE2 instructions for floating-point are automatically - detected and, where possible, enabled on platforms using the gcc - compiler. As a consequence, some arithmetic operations may have - different (more accurate!) results on some platforms, and - cross-platform consistency of Python arithmetic should be improved. - This applies particularly to Linux/x86. - - Issue #1580: On most platforms, use a 'short' float repr: for a finite float x, repr(x) now outputs a string based on the shortest sequence of decimal digits that rounds to x.
