For those that may read this or run into the same issue: this started
with the LLVM 12 upgrade in rustc nightlies. Therefore, please avoid
the very latest nightlies (>= nightly-2021-03-05) until [1] is
resolved.

To automatically setup a known-to-work nightly for Rust for Linux (the
one we use the most in the CI), run:

    rustup default nightly-2021-02-20
