+revert some altivec specific change on all ppc* except ppc64le*
+
+q66: "We should also throw in a revert of FFmpeg/FFmpeg@3a557c5 but only
+conditionally, for ppc* but not ppc64le* (the new code is valid for
+POWER8 VSX which LE targets as a baseline but not BE)"

+This reverts commit 3a557c5d88b7b15b5954ba2743febb055549b536.
