Fix build on big endian systems
Without this fix, the build was failing with:
/usr/bin/ld: perfunwind.o: in function `QDataStream::Version qToLittleEndian<QDataStream::Version>(QDataStream::Version)'
QtCore/qendian.h:207: undefined reference to `QDataStream::Version qbswap<QDataStream::Version>(QDataStream::Version)'
Fix it by explicitly casting QDataStream::Qt_DefaultCompiledVersion to
qint32 before calling qToLittleEndian.
