Pull request description:

  With a few minor changes, our macOS toolchain, and Guix, supports building for `arm64-apple-darwin` (Apple M1). Newer [`config.guess`](https://git.savannah.gnu.org/cgit/config.git/plain/config.guess) and [`config.sub`](https://git.savannah.gnu.org/cgit/config.git/plain/config.sub) are required (via autoconf 2.71), as support for recognising `arm64-apple-darwin` [was only recently added](https://git.savannah.gnu.org/cgit/config.git/commit/?id=2593751ef276497e312d7c4ce7fd049614c7bf80). A newer version of the macOS SDK (11.0+) is also required; I've taken this from Xcode 12.2.
