This happens with most targets requiring samples. They are skipped if you simply run "make
fate" but will try to run and fail if you call them explicitly.
fate-api-flac will still run before it fails with the h264 test if you call make fate-api.
Now, i'm not sure if there are other similar cases. After a quick glance every explicit
target seems to require samples for all tests or none. This would be the first with mixed

$(call DEMDEC, X, Y) implies the availability of the requested decoder and demuxer.
If said demuxer is still enabled in config.mak after configuring with "--disable-avformat"
then that's probably a build system bug.

Right, didn't realize this makes it dependent of ffmpeg.
I'll see if i can get around this later. Patch dropped until then.
