Look again.  From system-config/os-main.scm:

  (al utils)

And indeed, guile/modules/al/utils.scm has:

 (define (comma-separated . strings)
   "Return string by concatenating STRINGS with commas."
   (mapconcat identity strings ","))

You can copy the definition to your own configuration, or just 
replace it with the (trivial) MAPCONCAT call directly, or just use 
a comma-separated string to begin with.

Kind regards,
