Bug#751856: libav FTBFS on arm64

The build without neon is currently still in progress. The reduced feature build without neon built successfully and was uploaded to debian-ports arm64 unreleased. I'll probablly try your patch later when I come to do a full-feature build. Since the reduced feature build was uploaded build-depends for libav have become installable (partly due to the availability of the reduced feature build, some other issues also had to be dealt with). As expected the autobuild failed with the same error as my first attempt at a reduced feature build. I then applied the patch you linked and was able to successfully perform a build. Debdiff attatched and uploaded to debian-ports arm64 unreleased.
