That is what I tried first, but it does not work:
    (arguments
     `(#:phases
        (alist-replace
         'install
         (lambda* (#:key inputs outputs #:allow-other-keys #:rest args)
          (let ((install (assoc-ref %standard-phases 'install))
                (glibc (assoc-ref inputs "glibc"))
                (out (assoc-ref outputs "out")))
            (apply install args)
            (chdir "python")
            (substitute* "setup.py" (("/opt/include") (string-append glibc 
"/include")))
            (system* "python" "setup.py" "install" (string-append "--
prefix=" out))))
        %standard-phases)))

yields
...
In unknown file:
   ?: 1 [string-append #f "/include"]
In ice-9/boot-9.scm:

wrong-type-arg ...]

Indeed, the key of the hash table is "libc" and not "glibc". I think it 
would be better to change it to "glibc" (which is what both of us thought 
naturally that it was already). I think this occurrence needs to be 
changed:
  ./gnu/packages/base.scm:1091:      ("libc" ,glibc-final))))
in %final-inputs, and probably other places to be coherent.
