qmake: removing --no-undefined option for libs.

[axeljaeger]

Edit the appropriate mkspec from Qt. You can find it in the mkspecs-directory of your Qt installation.

That's done the trick. I editted "g++.conf" in "/usr/share/qt4/mkspecs/common", so the line containing "QMAKE_LFLAGS += -Wl,--no-undefined" was changed to remove the --no-undefined bit.

Thanks for the help.
