Maybe like this:

		  if (address == 0 && !dwarf2_per_objfile->has_section_at_zero)
		    {
		      /* This line table is for a function which has been
			 GCd by the linker.  Ignore it.  PR gdb/12528 */

		      long line_offset
			= line_ptr - bytes_read - dwarf2_per_objfile->line.buffer;

		      complaint (&symfile_complaints,
				 _(".debug_line offset 0x%lx uses address 0 "
				   "[in module %s]"),
				 line_offset, cu->objfile->name);
		      p_record_line = noop_record_line;
		    }
