I needed it to help me fixing a couple of bugs for old CPU, so it
ended up being implemented in the nsis script for scipy now (I will
add it to numpy installers too). So from now, any newly releases of
both numpy and scipy installers could be overriden:

installer-name.exe /arch native -> default behavior
installer-name.exe /arch nosse -> Force installation wo sse, even if
SSE-cpu is detected.

It does not check that the option is valid, so you can end up
requesting SSE3 installer on a SSE2 CPU. But well...
