D'OH! The problem is that the static submodules are compiled with the
debug_and_release flag in CONFIG. I wasn't aware that this is obviously
a default, or the default with QtCreator. My project doesn't define
debug_and_release anywhere.

Simply adding "CONFIG -= debug_and_release" in the *.pro files now
builds the static libs in debug mode and Qt5 release DLLs are no longer
imported.
