qtmultimedia/tests/auto/unit/qaudiodecoder/tst_qaudiodecoder.cpp
Friedemann Kleint b7d2215332 Unit test qaudiodecoder: Do not rely on qCompare(bool, int,...). 
The overload was added for NokiaX86 and RVCT and is bound for
removal.

Task-number: QTBUG-47260
Change-Id: I8eb0333e0e20323ab20f361186d9a47fd3ab9f24
