Seems to fix it. While we're here, maybe we should clean up the Shellcheck warnings, and note why we should ignore the return value in a comment:

$ shellcheck --shell=bash build-support/setup-hooks/auto-patchelf.sh

All the SC2154 warnings look like they're all input variables, so those can probably be silenced FWIW.

Let's keep this targeting master, rebuilds of packages that need patchelf are typically fast.

Overall looks good, a comment on ldd to explain why we're ignoring that return would be helpful before committing but I'm approving since others are blocked on this review.

I added a comment explaining why we return on a failing ldd/sed command.

What's the reason for this? The file is not executable.

I added this to make shellcheck happy.

codeowners: Add myself to autoPatchelfHook
47d1533 
I really hate the very concept of this file (the reason being that I
think "owner" implies some form of BDFL rather than just being
notified), but since there were recent[1] changes[2] in auto-patchelf.sh
which I missed it's probably a good idea to add myself there solely for
being notified, because ofborg can't seem to infer maintainer
information here.

To make indentation consistent with all the other entries in the
codeowners file, I also re-indented the other entries in the "Nixpkgs
Internals" block.
