"""Provides a fake @fuchsia_sdk implementation that's used when the real one isn't available.
This is needed since bazel queries on targets that depend on //:gtest (eg:
`bazel query "deps(set(//googletest/test:gtest_all_test))"`) will fail if @fuchsia_sdk is not
defined when bazel is evaluating the transitive closure of the query target.
See https://github.com/google/googletest/issues/4472.
