To override the variable assigned in the Makefile [1] you are right to
offer it as an argument to 'make'. [2] I'm not sure why that's not
working. I would just replace it in situ:

    #:phases (modify-phases %standard-phases
              (add-after 'unpack 'fix-prefix
               (lambda _
                (substitute* "Makefile"
                 (("/usr/local") $output)))))

Kind regards
Felix
