I’d be in favor or creating a separate package derived from gcc that has
Fortran enabled:

  (define-public gfortran
    (package (inherit gcc-4.8)
      (name "gfortran")
      (arguments
        ;; something that does --enable-languages=fortran
        )))

For code that fiddles with --enable-languages, see the definition of
‘gcc-boot0’ in base.scm.

Probably this should be factorized and made available in a nicer way:

  (define (gcc #:key (languages '("c" "c++")))
    "Return a GCC with the given LANGUAGES..."
    (package ...
       ...))

HTH,
Ludo’.
