Thanks! Sorry I didn't build asymptote (as I don't have a wish to build
gigabytes of texlive), but I looked at the source and I see there are
"autoloads" cookies in "<asymptote>/base/asy-mode.el", so it would also
be good to generate "asymptote-autoloads.el" file.
This file will be automatically loaded by emacs, and a user will not
have to do any additional settings in ".emacs", as ".asy" files will be
opened in "asy-mode" automatically.
For example, you may look at (gnu packages emacs) module to see how
"autoloads" file are generated using 'emacs-generate-autoloads'
procedure. I write some notes below, that seems appropriate to me, but
I'm not going to test the patch because of texlive (sorry again). I
hope other people will do.

You will need to add (guix build emacs-utils) module here, and:
#:imported-modules (,@%gnu-build-system-modules
(guix build emacs-utils))

Overall this phase would look like this (not tested):
(add-after 'install 'install-emacs-data
(lambda* (#:key outputs #:allow-other-keys)
;; Install related Emacs libraries in an appropriate location.
(let* ((out (assoc-ref outputs "out"))
(lisp-dir (string-append out "/share/emacs/site-lisp")))
(for-each (cut install-file <> lisp-dir)
(find-files "." "\\.el$"))
(emacs-generate-autoloads ,name lisp-dir))
#t))
Note that I added #t to the end of the phase because if a phase succeeds
it should return "not false" value. I think it's ok to add #t to the
other phases in this patch.
