Rollback of commit 27cd7f6bb4a02f56f9ad73e57e71e69a1c00d5ea.

*** Reason for rollback ***

Rolling forward, intentionally breaking loading phase (and therefore `bazel fetch`) for android_binary in Bazel if no android_sdk_repository is set up.

Will not submit until Tensorflow's use case is cleaned up in https://github.com/tensorflow/tensorflow/pull/6225.
