I think building it with SSE3 is better than excluding the architecture
entirely. And FYI, requiring SSE3 is not really allowed even for x86_64 (you
are allowed to assume only SSE2), so by that argument, there is no
architecture left.
Of course, a better solution would be to fix the package to work on all CPUs
you support. But if upstream doesn't care, it's going to be a problem. :-(
We have a similar issue with QtWebEngine, because Chromium/V8 upstream
requires SSE2 in their JIT and there is no interpreter fallback. (They are
now working on an "interpreter" mode, but it is not a real interpreter
fallback either, some stuff still uses the JIT.)
