Yes, it moves things to configure where many filters already have
assorted non lavfi dependencies listed there (fft, etc), so the end

for each OBJS entry is IMO worth the change.

Ok. Since you have a patchset removing framesync and renaming framesync2
I'll wait until that's committed before sending the aforementioned change.
