Sorry about that. cctools was reverted back to cctools-port as part of #322388, darwin.binutils(.bintools) being the effective replacement for cctools-llvm in most cases.

When #307880 is merged, dwarfdump will be found in ld64 since it comes from that upstream. cctools-apple and cctools-llvm will be added to darwin-aliases.nix, preventing their use in nixpkgs. There will be a follow-up treewide PR adding an alias for cctools-port.

Update: This was a good PR because it found a mistake in my ld64 derivation. dwarfdump comes from LLVM. I don’t know why I thought it was an alias for unwinddump. I’ll also fix #307880.

The change LGTM for master. I’m going to go ahead and merge it, so I can pull it into my ld64 PR with the change to use the ld64 package from cctools-llvm.
