Move DT_RELR tag setting to elflink.c
This makes the code setting DT_RELR tags generally available. Many
targets will be able to use the defaults. Those that can't should set
up sh_entsize for .relr.dyn output section before reaching the dynamic
tag code in bfd_elf_final_link.
* elflink.c (bfd_elf_final_link): Set up DT_RELR tags and sh_entsize.
* elfxx-x86.c (_bfd_x86_elf_finish_dynamic_sections): Don't do any
of that here.
