It is independent of a Qt 3 installation.

This option will prevent the Qt3Support module (of Qt 4) from being 
built. That saves a few compilation minutes.
And -more important- it will throw out the code in QtCore/Gui/etc. which 
is inside '#ifdef QT3_SUPPORT' blocks. That does not only save a few 
bytes in the binary, but also a few cpu cycles by preventing Qt3Support 
related runtime checks and tweaks.

Good luck with the build :)
