> AFAIK gcc does not enable SSE3 and SSE4 on X86_64 by default.

Linux now supports multiple variants of the same function, one variant per CPU type, the binding is done when a library is loaded. But I don't know how to implement that :-(

There is target_clones("sse4.1,avx") the function attribute in GCC for example. It compiles a function twice, once for generic CPU, once for SSE4.1.

See also ifunc: "indirect function", "CPU dispatch" or "function resolver".
