I see. I think it's fine if qtestlib doesn't have bc. (That said, from
what I can tell only the above change is required for testlib to be bc
possible)

The reason I added the above change was not bc related at all. The
problem was qtest.h ends up including qwindowsysteminterface_qpa.h.
After the rename, this file would become qwindowsysteminterface_p.h.
This means that for any of the auto tests to compile, I need to add Qt
+= gui-private somehow (many test just do QT = core testlib). I tried
and failed trying to fix qtAddLibrary(QtTestLib) to add gui-private
automatically. So, I resorted to the easier solution above.
