Would the following work in the mean time ?
1. Adding the following to gnu/packages/linux.scm :
(define-public linux-libre-config variant
(package
(inherit linux-libre)
(native-inputs
(let ((conf (kernel-config (or (%current-target-system)
(%current-system))
#:variant variant)))
`(,@(alist-delete "kconfig" (package-native-inputs linux-libre))
("kconfig" ,conf))))))
2. Adding this to your OS definition config.scm :
(operating-system
...
(kernel (linux-libre-config "4.6-vince")))
3. putting the kconfig file into:
gnu/packages/linux-libre-4.6-vince-x86_64.conf
If that's OK, I can prepare a patch adding the missing pieces...
