	* elf/dl-open.c (dl_open_worker): If DST is used in SUID program punt.
	* elf/dl-deps.c (expand_dst): Likewise.

	* elf/dynamic-link.h: Set DT_SYMBOLIC, DT_TEXTREL, and DT_BIND_NOW
	based on DT_FLAGS value.

	* elf/do-lookup.h: Remove reference_name parameter, add undef_map.
	Add test for symbols marked STV_HIDDEN.
	* elf/dl-lookup.c (_dl_lookup_symbol): Remove reference_name parameter,
	add undef_map.  Compute reference_name locally.  Update call to
	do_lookup.
	(_dl_lookup_symbol_skip): Likewise.
	(_dl_lookup_versioned_symbol): Likewise.
	(_dl_lookup_versioned_symbol_skip): Likewise.
	* elf/dl-libc.c: Update call to _dl_lookup_*symbol.
	* elf/dl-runtime.c: Likewise.
