For example, SSE3 instructions set is one of the minimum requirements

For that kind of thing, add a runtime test for required CPU features at
startup.
That's what they actually do.

[dt_init] unfortunately we depend on SSE3 instructions at this time.
[dt_init] please contribute a backport patch (or buy a newer processor).
That may not be necessary if the app already fails in a friendly way on
old CPUs (as opposed to hanging or mysterious crashes).
