Using Guile in a Makefile

[johol]

I'm using GNU Make 4.4 compiled from source with Guile support in Linux 
and I try to understand how to use it. Below is my first attempt for a 
trivial Makefile using Guile

---- 8< ----
define FNORD
;; Simple initial Guile-test
(define (fnord value)
  value)

#f
endef

# Internalize the Guile code
$(guile $(FNORD))

FOO = $(guile (fnord “F N O R D”))
$(info $$FOO is [$(FOO)])

fnord:
        for i in "$(FOO)"; do echo $$i; done
---- 8< ----

and this happens when I run GNU Make

$ make --version

$ make fnord
$FOO is [)]
for i in ")"; do echo $i; done
)
$

I guess I have made some error in the Makefile? Or does the make binary 
not have any Guile support? How can I tell if that is the case?

It does not matter if I change the implementation of Guile fnord 
function to
(define (fnord value)
  17)
or
(define (fnord value)
  "fNoRd")
or
(define (fnord value)
  (format #t "fNoRd"))

I still get a single ')' as the result from calling the Guile 'fnord' 
function...


Also I tried running GNU Make with option '-d' like this (replaced lots 
of text with '...')
$ make -d fnord
