-Bsymbolic is not for PIEs

Despite PR19615, it doesn't make sense to use -Bsymbolic with PIEs.
Dynamic symbols in an executable won't be overridden anyway.

	* ld.texi (-Bsymbolic, -Bsymbolic-functions): Don't mention PIEs.
	* ld.h (symbolic_enum, dynamic_list_enum),
	(args_type <symbolic, dynamic_list>): Move to..
	* lexsup.c (parse_args): ..here, using auto vars opt_symbolic
	and opt_dynamic_list rather than command_line fields.  Only
	act on -Bsymbolic and -Bsymbolic-functions for shared library
	output.  Free dynamic_list.
