+  if (bfd_arch_bits_per_address (link_info.output_bfd) < (sizeof (bfd_vma) *
8))
+    {

It doesn't work for x32 which has has 64-bit arch address and 32-bit
pointer.

+      segment_type * seg;
+      bfd_vma max = ((bfd_vma) 1) << bfd_arch_bits_per_address
(link_info.output_bfd);
+
+      for (seg = segments; seg; seg = seg->next)
+       if (seg->value >= max)
+         einfo (_("%P%X: Segment %s address %V is bigger than maximum address
%V\n"),
+                seg->name, seg->value, max - 1);
+    }
