Hi Fangrui,

> If a.so contains an SHT_RELR section, objcopy a.so will fail with:

Approved - please apply.

PS. I wonder if this particular code:

+	if (hdr->sh_type == SHT_REL)
+	  size = (bfd_size_type) bed->s->sizeof_rel;
+	else if (hdr->sh_type == SHT_RELA)
+	  size = (bfd_size_type) bed->s->sizeof_rela;
+	else
+	  size = (bfd_size_type) bed->s->arch_size / 8;

Should be extracted into its own function.  I imagine that
is going to be needed in other locations in the BFD library....
