I am only new to Guix, the most straight forward I found was to use the
`build-program' phase.

I followed StumpWM as an example[1].

--8<---------------cut here---------------start------------->8---
      (arguments
       (list
        #:phases
        #~(modify-phases %standard-phases
            (add-after 'create-asdf-configuration 'build-program
              (lambda* (#:key outputs #:allow-other-keys)
                (build-program
                 (string-append (assoc-ref outputs "out") "/bin/stumpwm")
                 outputs
                 #:entry-program '((stumpwm:stumpwm) 0)))))))
--8<---------------cut here---------------end--------------->8---

This works to my understanding by inserting a `bulid-program' step after
the other build phases.  It generates a separate asd file and evaluating
it with the `program-op' build operation is ASDF.  There is no easy way
I could see to use an existing `asdf:make' presumably this is because
redirecting the output file is not possible.

The `build-program' method is declared in guix/build/lisp-utils.scm[2]
it also takes a `compress?' keyword argument if you need it, the rest of
the flags are pretty much automated.
