Description: ppc: Fix compilation for ppc64le
Origin: upstream, http://patches.libav.org/patch/50835/

Patch taken from
https://bugs.launchpad.net/ubuntu/+source/libav/+bug/1263802,
with some minor fixups.

This fixes compilation for this target (tested with a cross compiler),
but it's completely untested in practice so far (qemu doesn't support
it yet, and I don't have any such hardware to test it on).
