* elf-bfd.h (elf_symbol_type): Add version field.
	* elfcode.h (elf_slurp_symbol_table): Set version field.
	* elflink.h (elf_link_add_object_symbols): When creating an
 	indirect symbol for a default version symbol, set DEF_DYNAMIC if
 	appropriate.  Set up an indirection from the nondefault version of
	the symbol as well.
	(NAME(bfd_elf,size_dynamic_sections)): Call
	elf_link_assign_sym_version before checking whether there are any
	versions.  Always record the version name as a dynamic symbol.
	Initialize counters.
	(elf_link_assign_sym_version): After finding a version, see if a
	symbol should be forced to local scope.  Create a new version
	definition if appropriate.
	(elf_link_output_extsym): Correct indirect symbol handling.
	* elf.c (bfd_elf_print_symbol): Print version information.
	(bfd_section_from_shdr): Turn version sections into BFD sections.
	(elf_fake_sections): Only copy cverdefs and cverrefs into sh_info
	if sh_info is not already set.

	sections.
