libdw: Handle empty location expression for (indirect) DIE locations. When dwarf_getlocation_implicit_pointer and dwarf_getlocation_attr refer to a DIE that doesn't contain a DW_AT_location then don't generate an error, but return an empty location expression to signal the actual value pointed to is not available. This isn't invalid DWARF. Also make sure that __libdw_intern_expression handles empty location expressions. Signed-off-by: Mark Wielaard <mjw@redhat.com>
