When executing step 3 I get this:

$ RUSTC_WRAPPER=./rustc-rpath.sh cargo install --locked
[...]

rustc should be finding librustc.rlib at the path ~/.rustup/toolchains/nightly-2020-03-22-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-gnu/lib/librustc-f2346a014cb63e11.rlib. If that file is missing on your system, you may need to add the rustc-dev component to the toolchain. Please run rustup component add --toolchain nightly-2020-03-22 rustc-dev and then try the build again.

If adding the rustc-dev component doesn't help, please run cargo build --locked --verbose (without setting RUSTC_WRAPPER) and post the results.

Adding rustc-dev works. Thanks.

Thanks, I've updated the README
