Building universal project library with qt5 on mac os 10.6.8 gcc4.2.1

[aidush]

Hallo everyone,
I am migrating project from Qt 4.7.3 where are universal binaries to Qt 5.3.2 where it is not possible to build them : http://qt-project.org/doc/qt-5/macosx.html.

So I built 32 and 64bit libraries and joined them with LIPO command.

Question is if it is no longer possible to built my project as universal binary with qt 5.3.2(even if I have have them with LIPO) Do I need to produce separately 32 bit and 64bit and then joined them as for Qt? Is there no simplier way how to do it using qmake?

thanks for answer in advance
