Here's one way to do it:

%%%%
\version "2.19.82"

\relative c {
    \clef "bass"
    \repeat unfold 10 {
         g2. g4 |
    }
    \break
    \once \override Staff.Clef.before-line-breaking = #(lambda (grob)
      (and (eq? LEFT (ly:item-break-dir grob))
        (set! (ly:grob-property grob 'X-extent) '(-2 . 2))))
    \clef "tenor"
    \repeat unfold 7 {
         g8 g g2.
    }
}
%%%%
