elf_backend_dtrel_excludes_plt
Now that all targets creating .rel.plt/.rela.plt use the ELF hash
table shortcut srelplt, the generic ELF code can set up DT_RELSZ/
DT_RELASZ and DT_REL/DT_RELA for targets that don't want PLT relocs
included in those tags.
* elf-bfd.h (struct elf_backend_data): Add dtrel_excludes_plt.
* elfxx-target.h (elf_backend_dtrel_excludes_plt): Define.
(elfNN_bed): Init new field.
* elflink.c (bfd_elf_final_link): Add and use htab variable. Handle
dtrel_excludes_plt.

DT_RELASZ code.
