Cannot select g++ compiler when building Android examples with Qt 5.9.8

Looks like it's not possible to deploy the forthcoming Qt 5.9.9 Android applications with the Qt Creator versions found from the online installer. (Also makes it impossible to do automated deploy testing for Qt 5.9.9, since there comes no compatible Qt Creator version and the automated tests are run using the binaries one can download and install via online installer.)  The build succeeds, but when trying to deploy an error dialog saying: "Detected problems with API compatibility (visit g.co/dev/appcompat for more info)."

Also it's not possible to change the compiler to g++ in the 'Kits'. It automatically uses clang compiler (ndk r10e set as the ndk in 'Device' -> 'Android').

Should it be possible to deploy Qt 5.9.8 (5.9.9) Android applications with the QtC versions found from the online installer?
