The Makefile uses gcc, even when compiling natively. But when 
cross-compiling, it needs to use a cross-compiler.

You will need to replace 'gcc' by (cc-for-target):

(replace 'configure
   (lambda _
     (substitute "Makefile"
       ;; For cross-compilation.
       (("\\bgcc\\b") #$(cc-for-target))
       ;; Stripping is already handled by gnu-build-system.
       (("\\bstrip\\b") ":"))))
