Bazel Toolchains

This directory contains toolchains config generated for Bazel RBE and Docker sandbox.

To regenerate toolchain configs, update the docker image information in rbe_toolchains_config.bzl and run following command in an environment with the latest Bazel and Docker installed:

toolchains/regenerate.sh

This will generate configs in toolchains/configs, check in those files so they can be used in CI.
