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.

	dtrel_excludes_plt.

	DT_RELASZ code.
