Arch Linux

Description:

When trying to build the basic hello world I get a linking failure:

```

There's a recent bug report in gentoo about rust+musl with identical error messages: https://bugs.gentoo.org/903607

It was fixed like this:

https://github.com/orbea/gentoo/commit/31661253a5b77ed18e38fc27fa22ebb9deca8257

The commit message states there was a change in LFS64 symbols in musl 1.2.4, which was released 2 months ago in Arch Linux.

Using the `x86_64-unknown-linux-musl` files from rustup still works on Arch Linux.
