Subject: bug#63288: 30.0.50; Emacs 30 packages fail to build with native comp on some machines

In https://github.com/nix-community/emacs-overlay/issues/318, we
received a report about failed external-package builds when using
Nix, which has some additional plumbing including
https://github.com/nixos/nixpkgs/blob/abcc3146aeb06b8d2ded75bddac3a63544a6be7e/pkgs/build-support/emacs/melpa2nix.el#L26-L32.

It was observed that reverting
https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=ea9831bb3cb4878273f6f848051c9b8c3c76d5f1
would resolve our issue.

On my own machine, I don't always encounter the build failure (happened
to me once a few weeks ago, and then again today).
