I don't believe this patch is sufficient.  It seems that the variable
'native-comp-eln-load-path may also need to be tweaked.  The path to the
"native-lisp" directory needs to be specified absolutely to make it not
be dependent on the invocation-directory.  Details below.

#+begin_src bash :results replace
  emacs --batch --eval "(message \"%s\" (car (split-string (describe-function 
'describe-function) \"\n\")))"
#+end_src

#+RESULTS:
: Type q in help window to delete it
: describe-function is an autoloaded interactive byte-compiled Lisp

#+begin_src bash :results replace
  type emacs
  ls ~/.guix-profile/lib/emacs/29.2/native-lisp/29.2-e9db68ab/help-fns.eln
  ls ~/.guix-profile/lib/emacs/29.2/native-lisp/29.2-e9db68ab/*.eln | wc -l
  ls ~/.guix-profile/lib/emacs/native-site-lisp/29.2-e9db68ab/*.eln | wc -l
  emacs --batch --eval "(message \"%s\" native-comp-eln-load-path)"
#+end_src

#+RESULTS:
: emacs is hashed (/home/user/.guix-profile/bin/emacs)
: /home/user/.guix-profile/lib/emacs/29.2/native-lisp/29.2-e9db68ab/help-fns.eln
: 1715
: 236
: (/home/user/.emacs.d/eln-cache/ 
/home/user/.guix-profile/lib/emacs/native-site-lisp ../native-lisp/)

#+begin_src bash :results replace
  emacs --batch --eval "(message \"%s\" (progn (add-to-list 
'native-comp-eln-load-path 
\"/home/user/.guix-profile/lib/emacs/29.2/native-lisp\") (car (split-string 
(describe-function 'describe-function) \"\n\"))))"
#+end_src

#+RESULTS:
: Type q in help window to delete it
: describe-function is an autoloaded interactive native-compiled Lisp
