[PyQt] Notes on Building PyQt for Qt v4.4rc1

[Phil Thompson]

In theory (if Qt maintains backwards compatibility) then the current version 
of PyQt should build against Qt v4.4rc1. However there is an incompatibility 
when using gcc.

The workaround is to comment out the line "QMAKE_LFLAGS += -Wl,--no-undefined" 
in mkspecs/common/g++.conf.
