You should just ignore the old LRS stuff.  The Dwarf 2 location lists
should be single symbols with the LOC_COMPUTED address class with a
`read_variable' method which use the PC from the frame it recieves to
choose the right location expression.

I guess I don't see how the old LRS stuff is in your way.
