It is not suitable because the resulting binary will depend on the
specific hardware on which it was built (while the goal is to make
builds as reproducible as possible).

AFAIK, the only platform on which SSE2 is guaranteed to be present is
amd64.

So I would disable SSE2 on all arches except amd64 (on which I would
enforce it).
