This has been broken in 25c8507818,
because the hacks for headers that are incompatible with building
for the host in libavcodec/tableprint_vlc.h have not been adjusted.
Moving AV_INPUT_BUFFER_PADDING_SIZE to defs.h which is valid for
both the target as well as the host allowed to remove some of the hacks.
