#1 The configure script fails to find qt-mt

[André Dahlqvist]

The configure script claims it can not find Qt (>= Qt
2.2.2). In config.log I can see that it has tried to
use -lqt to link against QT, even though -lqt-mt should
have been used on my system. The configure script needs
to check if the threaded or non-threaded libraries are
installed, and use the threaded ones if available.
