ELF: Add _bfd_elf_add_dynamic_tags 

All ELF backends with shared library support need to add dynamic tags.
Add dt_pltgot_required and dt_jmprel_required to elf_link_hash_table to
indicate that DT_PLTGOT and DT_JMPREL are required dynamic tags.

1. Add _bfd_elf_add_dynamic_tags to add common dynamic tags.
2. Add _bfd_elf_maybe_vxworks_add_dynamic_tags to add common VxWorks
dynamic tags.

	* elf-bfd.h (elf_link_hash_table): Add dt_pltgot_required and
	dt_jmprel_required.
	(_bfd_elf_add_dynamic_tags): New.
	* elf-m10300.c (_bfd_mn10300_elf_size_dynamic_sections): Call
	_bfd_elf_add_dynamic_tags.
