A similar check exists in src/corelib/plugin/qlibrary.cpp:isPlugin() [1] as
well but it's a bit less paranoid and will refuse to load a plugin if it
was built with later major Qt release (4.x). This still does not work with
symbol files well. So either we need to bump symbol versions to the
current 4.x series each new major release or just remove that check.

errorString = QLibrary::tr("The plugin '%1' uses incompatible Qt
library. (%2.%3.%4) [%5]")
