I couldn't figure out a way around this because the main Amarok app
uses Meta::Track for everything.  For example, all the dynamic
playlists code uses Meta::Track.  So if I don't add the three
fingerprinting functions to Meta::Track, then the dynamic playlist
can't make use of any fingerprinting code.  I tried to mitigate this
problem by declaring the do-nothing fingerprinting functions as normal
virtual (instead of pure virtual) in Meta::Track so that any class
that doesn't use fingerprints can just inherit the do-nothing
functions.  If you can suggest a better way to do this, please do.
