It depends on the case. Which case are you talking about?

The different MMX, SSE, SSE2, SSE3 options are selected by the
"Architecture Variant" options. However, the SSE4 options are not
selected by any "Architecture Variant" that currently exists in
Buildroot. I'd prefer not to have such dead/unused code, so either the
corresponding Architecture Variants should be added, or the SSE4
related options should not be added for now (until someone actually
needs those Architecture Variants).
Regards,
Thomas
