Why ist it that Rust target aarch64-unknown-freebsd cannot be installed on FreeBSD when it is supposed to be a "Tier 2 with Host Tools" target, according to the docs?

For reference:

Error message I get, on FreeBSD 15.1:

==> qemu.qemu: + /opt/rust/cargo/bin/rustup target add aarch64-unknown-freebsd i686-unknown-freebsd
==> qemu.qemu: error: toolchain '1.96.0-x86_64-unknown-freebsd' has no prebuilt artifacts available for target 'aarch64-unknown-freebsd'
==> qemu.qemu: note: this may happen to a low-tier target as per https://doc.rust-lang.org/nightly/rustc/platform-support.html
==> qemu.qemu: note: you can find instructions on that page to build the target support from source

Regards.
