	PR 7047
	* configure.in: Bump version.
	* configure: Regenerate.
	* elflink.c (_bfd_elf_link_assign_sym_version): Continue matching
	against version nodes when a global match is a wildcard.  Similarly
	continue matching on local wildcard matches, rather than only
	continuing for "*".  Have any global wildcard match override a
	local wildcard match.  Correct logic hiding unversioned symbol.
	(bfd_elf_size_dynamic_sections): Update for changes to struct
	bfd_elf_version_expr.

	for changes to struct bfd_elf_version_expr.
	* ldlang.c (lang_vers_match, version_expr_head_hash): Likewise.
	(version_expr_head_eq, lang_finalize_version_expr_head): Likewise.
	(lang_register_vers_node): Likewise.
	(lang_new_vers_pattern): Likewise.  Ensure "literal" is set when
	no glob chars found in "pattern".
	(realsymbol): Correct backslash quote logic.
	* ld.texinfo (VERSION): Warn about global wildcards.
