Unfortunately this does not work for two reasons:

1. The i386 architecture and all buildds do support SSE2,
   but using it without runtime check is a baseline violation.
2. The software does use handwritten SSE, which won't compile
   on non-x86 architectures (the arm64 support in upstream
   master adds an alternative NEON implementation).
