Correction, it must be

> #:make-flags ,#~(list (string-append "PREFIX=" #$output) (string-append "CC=" 
> #$(cc-for-target))).

(#$(cc-for-target) instead of ,(cc-for-target)).

That makes the cross-build

./guix-cuf/bin/guix build --target=aarch64-linux-gnu -e '((@ (guix packages) 
package) (inherit (@ (gnu packages disk) dosfstools)) (arguments `(#:make-flags 
,#~(list (string-append "PREFIX=" #$output) (string-append "CC=" #$((@ (guix 
utils) cc-for-target)))) #:configure-flags (list "--enable-compat-symlinks"))))'

succeed for me, though I don't have an aarch64 to test it on.
The output from 'guix gc --references' only show a glibc-cross-... and 
gcc-cross-...-lib,
so presumably the cross-compiled package will work.
