Only ARMv4, ARMv5, ARMv6 and ARMv7-A is supported. Due to this, object files built out of ARM-optimized assembly code have the wrong architecture information, causing a failure at link time. Adding ARMv7-M support would be possible, but it doesn't exist yet in ffmpeg, and it's pretty unlikely that ffmpeg will ever be needed on an ARMv7-M platform, so this commit takes the simple approach of disabling ffmpeg for ARMv7-M.
