The problem is not so much the build part, but the clear separation I
was talking about. My experience with ATLAS convinced me the only way
to make sse work reliably is to detect the CPU arch at runtime;
compiling binaries incompatible on different arch is just not scalable
and confuse users.

Technically, to make this work, you need a clear different in the
codebase between the code which calls the C functions changed at
runtime, and the ones which are called by python. Hopefully, I will
have more to say within the end of the week

cheers,

David
