cargo wasix build error: `GLIBC_2.36' not found

[happybeing]

I'm trying to test WASIX on a Rust project by following the instructions in the announcement and not sure if this is where to ask. If not I'll move my question to wherever is appropriate.

All is well until I try cargo wasix build at which point I get an error because the wasix rustc appears to be built depending on libc 2.36, whereas Ubuntu 22.04 LTS uses libc 2.35:

$ cargo wasix build
/home/mrh/.rustup/toolchains/wasix/bin/rustc: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.36' not found (required by /home/mrh/.rustup/toolchains/wasix/lib/librustc_driver-239bacfa42cce6c3.so)
error: Could not execute rustc

Caused by:
    failed to execute "rustc" "+wasix" "--print" "sysroot"
        status: exit status: 1

I don't want to install libc 2.36 or upgrade to ubuntu 23 as these are dangerous and unstable things respectively.

Is this intentional, and is there a way around this?
