I've bisected the culprit to be #167945. @cbracken

Before building an engine tree with #167945, you will need to rerun gclient sync (or et fetch).

That will run the https://github.com/flutter/flutter/blob/master/engine/src/build/mac/apple_sdk.py script and initialize the engine/src/flutter/prebuilts/Platforms directory.
