Spectrum example does not work because of stripped out libfftreal

When trying to run the Spectrum example in examples/qtmultimedia/spectrum it will fail because libfftreal is missing.

holger@hmpf:~/Betas/Qt5.0.0beta2/5.0.0-beta2/gcc_64/examples/qtmultimedia/spectrum$ ./spectrum
./spectrum: error while loading shared libraries: libfftreal.so.1: cannot open shared object file: No such file or directory

This library is supposed to be build with the example when running qmake in the directory.

I assume its simply stripped away when packaging.
