Here’s a more complete example that works for me.

First, I have this linux-libre.scm file in my GUIX_PACKAGE_PATH:

--8<---------------cut here---------------start------------->8---
(define-module (linux-libre)
  #:use-module (guix gexp)
  #:use-module (guix packages)
  #:use-module (gnu packages linux)
  #:use-module (srfi srfi-1))

(define-public my-own-linux-libre
  (package
    (inherit linux-libre)
    (name "linux-libre-for-myself")
    (native-inputs
     `(("kconfig" ,(local-file "./my-kernel.conf"))
       ,@(alist-delete "kconfig" (package-native-inputs linux-libre))))))
--8<---------------cut here---------------end--------------->8---

In the same directory lies the file ‘my-kernel.conf’.

With this, I can do:

--8<---------------cut here---------------start------------->8---
$ guix build linux-libre-for-myself -n --no-grafts
The following derivation would be built:
   /gnu/store/23b25z660ahglylv5blm2l9cbrc639c2-linux-libre-for-myself-4.6.4.drv
$ guix gc --references 
/gnu/store/23b25z660ahglylv5blm2l9cbrc639c2-linux-libre-for-myself-4.6.4.drv | 
grep my-kernel
/gnu/store/pq885cy0bi73acwh1wdx4agn5y5vrf2z-my-kernel.conf
$ cat /gnu/store/pq885cy0bi73acwh1wdx4agn5y5vrf2z-my-kernel.conf
Fake kernel conf.
--8<---------------cut here---------------end--------------->8---

Does something similar works for you?

HTH,
Ludo’.
