Some Google projects like [protocolbuffers](https://github.com/protocolbuffers/protobuf/blob/main/build_defs/BUILD.bazel#L65) or [boringssl](https://github.com/google/boringssl/blob/b9232f9e27e5668bc0414879dcdedb2a59ea75f2/BUILD#L82) replies on checking `crosstool_top` value for whether it is an Android target or not. Adding a `default_crosstool` or `toolchain-libcpp` alias could be a workaround for the problem.
