Yes, I did test this on a sample of random Emacs packages and they built
fine with these changes.

Done! It's good to know how to handle these pesky nils at last!

30116, good catch!

Hmm, I think I'd rather leave it there; the alternative implies
replacing the `patch-el-files' phase in the package definition, and this
would involve copy-pasting the modified phase code which is a bit
messy. I'd also rather spare someone from having to investigate this
problem again until 30116 is merged into master.

Does it make sense?

Done. All patches attached!

Thanks for reviewing :)

Subject: [PATCH 1/7] emacs-build-system: Add set-emacs-load-path phase.

This generalizes the mechanism by which the Emacs dependencies are made visible,
so that any build phase can make use of them.

* guix/build/emacs-build-system.scm (%legacy-install-suffix): New variable.
(%install-suffix): Redefine in terms of %legacy-install-suffix.
(set-emacs-load-path): Add new phase used for dependency resolution.
(build): Remove ad-hoc dependency discovery mechanism.
(emacs-input->el-directory): Add new procedure.
(emacs-inputs-el-directories): Use it.
(package-name-version->elpa-name-version): Fix typo.
(%standard-phases): Include the new `set-emacs-load-path' phase. Refactor to
make the ordering of the phases clearer.
* guix/build/emacs-utils.scm (emacs-byte-compile-directory): Remove the
optional `dependency-dirs' argument, which is now obsoleted by the
`set-emacs-load-path' phase.
