Fix failure to build QtQuick with LTO

Browse Source 
The presence of the inline QTestFontEngine's constructor causes a linker
failure because QFontEngineBox isn't exported. I'd say this is a
compiler bug (GCC 4.9), but it's an easy workaround and a difficult
testcase.

typeinfo for QTestFontEngine: error: undefined reference to 'typeinfo for QFontEngineBox'
vtable for QTestFontEngine: error: undefined reference to 'QFontEngineBox::glyphIndex(unsigned int) const'
