I do not know about ffmpeg, but MPlayer does not set any of these for a
"generic" build, and they should not be.
-maltivec is only set because otherwise the altivec stuff will not
even build (and which is the thing that creates all the problems and
some of us consider so horribly broken - support for explicit use of
extensions should not be mangled into one option with automatic use).
