OpenBSD -current (and the already-tagged but not-yet-released 5.5) builds
x264 with Clang's assembler to enable the assembly code.

The FFmpeg port is built against x264, so building x264 against FFmpeg would
give a circular build dependency. It could potentially be done differently by
adding a bootstrap flavour of the x264 port, but that's a lot of complication
for something which I don't recall seeing any requests on-list for before.
