DW_FORM_ref_addr dosn't work

DW_FORM_ref_addr can reference an entry in a different compilation
unit, even from a different shared object. But die_ref_table only
contains DIEs in one single compilation unit. Why do we do that? What
is the best way to fix it?

BTW, I am enclosing my quick dirty hack for reference.
