I didn't get anything to work using an override of  #'bound-details
#'right #'Y, but you can override 'after-line-breaking like so:

\version "2.17.7"

#(define flat-gliss
  (lambda (grob)
    (let ((left-Y (assoc-get 'Y (ly:grob-property grob 'left-bound-info))))
      (ly:grob-set-nested-property! grob '(right-bound-info Y) left-Y))))

\relative c'' {
  \override Glissando #'after-line-breaking = #flat-gliss
  \override Glissando #'thickness = #5
  c1\glissando
  g'\glissando
  g,
}

HTH,
