Qt (qmake, whatever) is aware that it has phonon support.

If you compile Qt w/o phonon you should not have phonon support in e.g. 
webkit. (Even if configure would detect it you'd have to install 
kdesupport/phonon before Qt - what's not possible)

If you're not interested in phonon support outside KDE apps (i.e. for plain Qt 
apps), there should however be no problem by compiling Qt w/o Phonon as cmake 
will (also later on) detect phonon and compile the app with it.
