Additional context

All but one of the symlinks in the instruments.tar.gz tarball have their permissions set to 0000. This causes noBrokenSymlinks to fail silently¹ at readlink on systems like Darwin/macOS that actually care about symlink permissions. It also seems to be the reason that turning on dontRewriteSymlinks on Darwin was necessary.

System metadata

• system: "x86_64-darwin"
• host os: Darwin 19.6.0, macOS 10.15.7
• multi-user?: yes
• sandbox: no
• version: nix-env (Nix) 2.24.10
• channels(root): "nixpkgs"
• nixpkgs: /nix/var/nix/profiles/per-user/root/channels/nixpkgs

Note that while that channel is currently behind a bit on my machine, I'm ignoring it and using flakes when I reproduce this. I can also pull the nix-info -m from the GitHub runners where I originally saw this if you need them.
