Several people have already urged you not to build a string
at a time, but to make the whole list in one expression.
To answer your question though:
If you insist on adding one string at a time

 (define (add-to-output str)
   (set! output-list (cons str output-list)))
 (add-to-output (sgids pref-login))
 (add-to-output (gids))
 (add-to-output (getd pref-login))
