Error during build: rust-lld: error: undefined symbol:

[jessienab]

Not sure why this is failing to build on Arch Linux as all the cargo packages and rust/rust compilation applications match what the Github runner were using, and I can't find any mention of zstd within "Linux dependencies" for the runner.

[user@eaa6dde7ebc7 ~]$ rustup --version
rustup 1.29.0 (2026-03-23)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: the currently active `rustc` version is `rustc 1.96.1 (31fca3adb 2026-06-26)`
[user@eaa6dde7ebc7 ~]$ rustfmt --version
rustfmt 1.9.0-stable (31fca3adb2 2026-06-26)

[user@eaa6dde7ebc7 ~]$ ld.lld --version
LLD 22.1.6 (compatible with GNU linkers)
