Qt for Android Environment Variables

QT_ANDROID_NO_EXIT_CALL

In some cases, an Android app might not be able to safely clean all threads while calling exit() and it might crash. This is because there are C++ threads running and destroying these without joining them terminates an application. These threads cannot be joined because it's not possible to know if they are running. This flag avoids calling exit() and lets the Android system handle this, at the cost of not attempting to run global destructors.
