bfd/

	* elflink.c (_bfd_elf_export_symbol): Adjust for globals and locals
	field changes.
	(_bfd_elf_link_assign_sym_version): Likewise.
	* elflink.h (size_dynamic_sections): Likewise.
include/
	* bfdlink.h (struct bfd_elf_version_expr): Remove match field.
	Add wildcard and mask fields.
	(BFD_ELF_VERSION_C_TYPE): Define.
	(BFD_ELF_VERSION_CXX_TYPE): Likewise.
	(BFD_ELF_VERSION_JAVA_TYPE): Likewise.
	(struct bfd_elf_version_expr_head): New.
	(struct bfd_elf_version_tree): Add match field.
	Change type of globals and locals fields
	to struct bfd_elf_version_expr_head.
ld/
	* ldlang.c: Include hashtab.h.
	(lang_vers_match_lang_c, lang_vers_match_lang_cplusplus,
	lang_vers_match_lang_java): Remove.
	(lang_vers_match): New function.
	(lang_new_vers_pattern): Initialize wildcard and mask
	fields, don't initialize match.
	(lang_new_vers_node): Use xcalloc.  Adjust for globals and
	locals field type changes.  Set match field.
	(version_expr_head_hash, version_expr_head_eq): New functions.
	(lang_finalize_version_expr_head): New function.
	(lang_register_vers_node): Call lang_finalize_version_expr_head.
	Search in hash table if not wildcard when looking for duplicates.
	* emultempl/ppc64elf.em (new_vers_pattern): Don't bother with
	duplicate checking.  Initialize all fields of dot_entry from entry
	with the exception of pattern and next.
