x11-dl fails to link when building a x86_64-unknown-linux-musl target on Ubuntu 20.04 when using rust 1.72+.

Notably:

  = note: some `extern` functions couldn't be found; some native libraries may need to be installed or have their path specified
  = note: use the `-l` flag to specify native libraries to link
  = note: use the `cargo:rustc-link-lib` directive to specify the native libraries to link with Cargo (see https://doc.rust-lang.org/cargo/reference/build-scripts.html#cargorustc-link-libkindname)

error: could not compile `musl-regression` (bin "musl-regression") due to previous error

Reproducing

I was able to isolate this to the most simple case.

cargo new --bin musl-regression && \
cd musl-regression && \
cargo add x11-dl
// main.rs
use x11_dl::xlib;

fn main() {
    let _xlib = xlib::Xlib::open().unwrap();
}

We're going to invoke different containers and call this command inside them:

rustup target add x86_64-unknown-linux-musl && cargo build --release --target=x86_64-unknown-linux-musl

The containers we're invoking:

# works:
docker run --rm -it -v $(pwd):/workspace --workdir /workspace rust:1.71-bullseye bash
# doesn't work:
docker run --rm -it -v $(pwd):/workspace --workdir /workspace rust:1.72-bullseye bash
# works:
