So the sed seems to be applied to programs too instead of just object
files (I haven't verified but that's what it looks like with this).
That's why the stem is used ($(*F) instead of $(@F)) and appended with
'.o'.

But then, why is the stem truncated from dct-test to dct? I have no
idea either. Another rule somewhere?

Another thing: is it windows-specific? Without the patch, what do you
get in libavcodec/dct-test.d ?
