The Linux installers were linked against the release runner's glibc and
needed glibc 2.39: v0.3.0 (and v0.2.0) failed on the first line on
Debian 12 (2.36) and Ubuntu 22.04 (2.35) with "GLIBC_2.39 not found" --
found by the Rust phase 18 walk, step 7. Both Linux targets are now
x86_64/aarch64-unknown-linux-musl, built with cargo-zigbuild (zig is the
one C compiler `ring` needs for both musl targets; Ubuntu packages a
musl gcc for x86_64 only), and the package step refuses a Linux binary
that `file` does not call statically linked. Windows is unchanged.
Tried in rust:1-slim-bookworm: both targets build, both are "statically
linked", and the x86_64 binary runs.
