Looking at WebCore.pro, it does (still) not appear as if phonon support would 
be compiled /at all/ in if you don't pass -phonon

contains(DEFINES, ENABLE_VIDEO=1)

which is itself 0 due to 

contains(QT_CONFIG, phonon):DEFINES += ENABLE_VIDEO=1
else:DEFINES += ENABLE_VIDEO=0

still you'd not have Qt phonon support w/o compiling Qt with phonon support, 
yesno?
(or does Qt (meanwhile?) detect the system phonon and weirdly adds support if 
you explicitly added -no-phonon?!?)

If i move libQtPhonon out of the way, yes.

So the suggested way is to:
- compile Qt with -phonon
- compile kdesupport including phonon
- prefix kdesupport phonon to QTDIR, having it override the Qt variant
or
- replace QtPhonon with symlinks to kdesupport phonon (BC is guaranteed in 
either way)
- compile KDE
