Build failure: ncdu on aarch64-darwin on nixos release branch

[charlie-collard]

Steps To Reproduce

Steps to reproduce the behavior:

1. On aarch64-darwin: nix build 'github:NixOS/nixpkgs/526d051b128b82ae045a70e5ff1adf8e6dafa560#ncdu'

This commit is the latest on the nixos-23.11 release branch at time of writing

Additional context

There is another issue open here: https://github.com/NixOS/nixpkgs/issues/287861, but the error is different and they were using x86_64-darwin so I figured it was better to open another issue.

The build seems to be fixed on the unstable branch so I think something needs to be backported to the release branch:

nix build 'github:NixOS/nixpkgs/526d051b128b82ae045a70e5ff1adf8e6dafa560#ncdu'

I ran a bisect on the nixos-23.11 branch and it identified this commit as causing the failure.

ncdu is broken on unstable for aarch64-darwin as well.

@bspammer Hmm, that seems to be a red herring. Indeed, the build of the commit before that on hydra worked, but I can't reproduce it:

$ git checkout ac60eaff15a3a96bbec69d4316ab538f8f00d235
$ nix run .#ncdu -- --version
ncdu 2.3
$ nix build --rebuild .#ncdu

       For full logs, run 'nix log /nix/store/kvvdj4x6z1fcq3npnky1qx9q1v17l5cg-ncdu-2.3.drv'.

Interestingly, the same is true for zig itself:

$ nix build --rebuild .#zig
error: builder for '/nix/store/9437b781qs7zr12sqf9pwismjlksm5bw-zig-0.11.0.drv' failed with exit code 2;

So this might be caused by https://github.com/NixOS/nixpkgs/issues/299091
