Most ff_ symbols are now hidden by default.
That was a very recent change.
Of course I suspect that
a) possibly a few filters are broken, too (as said I did not test).
b) the hackish solution would be to add that RIFF tags to the list
   of ff_* symbols to be exported.

But just getting rid of the riff.h include would help some distros,
then they don't have to manually hack the build system to install it
(did you manually install that and some other headers?).
