VSX is indeed an extension to AltiVec, so having VSX implies having
AltiVec [0], so we can condition the altivec support on LE, on VSX being
available.
To be noted, however, is that ffmpeg has a configre switch dedicated to VSX:
--enable-vsx. We do not add support for that here, as we are just fixing
the AltiVec support. Adding VSX configure flag is left as an excercise for
a future feature addition.
