Oswald Buddenhagen d64abf8166 refuse to build examples inside the qt source tree stand-alone
doing so is somewhat likely to cause follow-up issues, as it turns the
source tree into a build tree as a side effect.

note that this change does not affect building examples inside an
install tree, even if doing that is still ugly.
