"""
This file assembles a toolchain for a Mac M1 host using the Clang Compiler and glibc.

It downloads the necessary headers, executables, and pre-compiled static/shared libraries to
the external subfolder of the Bazel cache (the same place third party deps are downloaded with
http_archive or similar functions in WORKSPACE.bazel). These will be able to be used via our
custom c++ toolchain configuration (see //toolchain/clang_toolchain_config.bzl)
