Coreutils v9.8 has a regression on Darwin that causes
`__CF_USER_TEXT_ENCODING` env var to get added to `env`’s output. This
causes a test failure. So get the variant of `env` from
darwin.shell_cmds instead (and `uname`, to avoid having both pkgs in the
closure).
I submitted a bug report to Coreutils, but it is not yet in the tracker
or list archives for me to link from here.
Somehow this was working before, but around 2025-10-23, something
changed on master, and nixpkgs-review would stop working on
https://github.com/NixOS/nixpkgs/pull/445078:
```
$ nix build -L github:NixOS/nixpkgs/pull/445078/head#lib3mf.dev
$ eza result-dev/include/
lib3mf/
$ nix build -L github:NixOS/nixpkgs/pull/445078/merge#lib3mf.dev
$ eza result-dev/include/
"result-dev/include/": No such file or directory (os error 2)
```
The headers are now installed in the build tree:
```

```
Maybe CMake 4.1.1 -> 4.1.2 changed something.
