Linking errors in qttools when cross-compiling for BB10

When you try to cross-compile the qttools module of Qt 5.0.1 (and also current 'stable' branch) against the BBNDK, you get linking errors for every application that links against QtHelp.

/opt/bbndk-1673/host_10_0_9_404/linux/x86/usr/bin/ntoarm-ld: warning: libQt5CLucene.so.5, needed by /mnt/archive/src/qt5/build.colt/qttools/lib/libQt5Help.so, not found (try using -rpath or -rpath-link)

The problem is that the linker on BB10 does not keep a dependency chain, therefor you'd have to specify explicitly all libraries (the directly and indirectly used).
