Can be simplified to

(when tests?
   (apply invoke "make"
           ;; "V=1"
           "SKIP_KNOWN_BUGS=1"
           "SKIP_INTERNET_TESTS=1"
           "check" make-flags))


+     `(#:tests? (if ,(%current-target-system) #f #t)

That's the default, no need to mention it again here.

+       #:make-flags
+       (let ((target ,(%current-target-system)))
+         (if target
+             (list (string-append "CROSS_COMPILE=" target "-"))
+             (list)))

Can be simplified:

#:make-flags
,(let ((target ,(%current-target-system)))
    (if target
        #~(list (string-append "CROSS_COMPILE=" ,target))
        #~'()))

(the #~ makes the phasing more explicit, if you go for that, I recommend 
turning the arguments into (arguments (list #:phases #~(modify-phases 
...) #:make-flags ...)), instead of using ` / , , to remain consistent.)
