Something weird is going on here with flutter, specifically why is 
flutter-engine-sdk-native expecting nativesdk-flutter-engine-sdk 
"host" tools to be deployed to the "target"-specific DEPLOY_DIR_IMAGE 
and not the SDK_DEPLOY...

But since both native.bbclass and nativesdk.bbclass remove 
MACHINEOVERRIDES, they should still point to the same default 
DEPLOY_DIR_IMAGE anyway...
