Rust will drop support for musl before 1.2.3

[22h49]

Is this a new report?

Yes

System Info

Void 6.6.23_1 x86_64-musl AuthenticAMD uptodate rFFF

Package(s) Affected

rustup-1.27.0_1

Does a report exist for this bug with the project's home (upstream) and/or another distro?

Yes, but this concerns Alpine Linux (of which versions with old musl are EOL): rust-lang/rust#121980.

I'm not really sure if this classifies as a bug or "requesting the update of a package" but this makes rust nightly currently unusable on musl, I'm aware that the discussion around updating musl is very large but if this issue is unproductive I'll close it.

Expected behaviour

rustc runs

Actual behaviour

$ rustc
Error relocating /home/[...]/.rustup/toolchains/nightly-x86_64-unknown-linux-musl/lib/libstd-3a22c2cec086c98b.so: pthread_getname_np: symbol not found

### Steps to reproduce

1. `xbps-install rustup`
2. `rustup install nightly`
3. `rustc`
