Comment (by cypherpunks):

 Look at `rewrite_elf_program_header()` from bfd/elf.c:
 {{{
       if (segment->p_type != PT_LOAD)
         {
           /* Remove PT_GNU_RELRO segment.  */
           if (segment->p_type == PT_GNU_RELRO)
             segment->p_type = PT_NULL;
           continue;
         }
 }}}
 It used to call by `setup_bfd_headers (ibfd, obfd)` from `copy_object()`
 of binutils/objcopy.c
