Commit 9db5ca87897340873a4606c651a37e0356e8f1a0 sets the default
qtDataDirectory to the value of qtInstallDirectory, which results in an
invalid path when appended to the SDK. This results in build failures
for Android when building with qbs. cmake builds are not affected as
the data directory is explicitly set in the build scripts.
