Hmm, try to patch it out of the source code.

Modify /gnu/packages/hurd.scm to be something like:

(define-public hurd
  (package
    [...]
    (arguments
     `(#:phases
       (modify-phases %standard-phases
         (add-after 'unpack 'patch-paths
           (lambda* (#:key outputs #:allow-other-keys)
             (substitute* "hurd/paths.h"
              (("\"/hurd/\"")
                (string-append "\"" (assoc-ref outputs "out") "\"")))
             #t))
         [...]
