Indeed, the audacity binary is not linked against libav{codec,format} 
but instead both libraries are loaded on demand. You even have to ask 
for it in the preferences dialog. At least, when configured with the 
--with-ffmpeg=system confflag, it finds the right ones (and not what 
is reported in #514333).

I am tempted to forcedly hack '-lavcodec -lavformat' into audacity's 
ldflags...

Yes, I have just built audacity 1.3.6-3 against the ffmpeg libraries 
from experimental on my alpha and it worked. I haven't actually tested 
loading, playing and saving files, though. No sound hardware on alpha...
