It's not just OS4, and I don't think it's broken. I have the same
problem under Linux with static builds. The flag means that libraries
aren't added if they aren't considered a dependency, and because the
media handler uses static initialization magic it won't be added.

I can fix it by changing the registration code to make an explicit
function call to register handlers. That has the disadvantage of
reintroducing ifdefs (though only into a small part of the code) and
headers.

Or we can hack at the configure and linking code to make sure everything
is linked as expected. Even in this case it's possible for a conforming
implementation not to initialize the static objects, so it won't
necessarily work on all platforms.

I favour the former option, even though it makes the code a bit messier
and means the separate MediaHandler{Ffmpeg,Gst,Haiku} headers are needed
again.

What do other devs think?
