SSE is not supported on all architecture.
Hurd is one among others.
If code makes use of SSE with no fallback option, then it is not
supported on this architecture.

configure etc... can detect if SSE is supported on current arch, and
sets SSE_ENABLED or something like that in config.h,but of course, code
must manage this and fallback to non-sse code in this case, if any.....
