Actually, we don't need \single.  Doh.

Just using ^ and _ is sufficient:

\version "2.18.2"

\language "english"

global = {
  \key gs \minor
  \time 6/8
  \clef treble
}

\new Staff {
  <<
    \new Voice {
      \relative c'' {
        \global
        \voiceOne
        % | <a' a'>4. ~ ( q8 <gs gs'>8 <fs fs'> )
        % \once \override Tie.rotation = #'(180 0 0)
        <<
          { <a_~>4. a8 gs fs }
          { <a'^~>4. a8 gs fs }
        >>
      }
    }
    \new Voice {
      \relative c'' {
        \global
        \voiceTwo
        \override NoteColumn.force-hshift = #1.4
        <ds fs>2.
      }
    }
  >>
}
