* elf/dl-lookup.c (dl_new_hash): New functions. cvs/fedora-glibc-20060710T2206
	(_dl_lookup_symbol_x): Rename hash to old_hash and don't compute
	value here.  Compute new-style hash value.  Pass new hash value
	and reference to variable with the old value to do_lookup_x.
	(_dl_setup_hash): If DT_GNU_HASH is defined, use it and not
	old-style hash table.
	(_dl_debug_bindings): Pass new hash value and reference to variable
	with the old value to do_lookup_x.
	* elf/do-lookup.h (do_lookup_x): Accept additional parameter with
	new-style hash value and change old-style hash value parameter to
	be a reference.  Reoganize functions to determine whether
	new-style hash table is available.  Only fall back on old-style
	table.  If old-style hash value is needed, compute it here.
	* elf/dynamic-link.h (elf_get_dynamic_info): Relocate DT_GNU_HASH
	entry.
	* elf/elf.h: Define SHT_GNU_HASH, DT_GNU_HASH, DT_TLSDEC_PLT,
	DT_TLSDEC_GOT.  Adjust DT_ADDRNUM.
	* include/link.h (struct link_map): Add l_gnu_bitmask_idxbits,
	l_gnu_shift, l_gnu_bitmask, l_gnu_buckets and l_gnu_chain_zero.
	* Makeconfig: If linker supports --hash-style option add it to all
	linker command lines to build DSOs.
	* config.make.in: Define have-hash-style.
	* configure.in: Test whether linker supports --hash-style option.

	* elf/dl-misc.c (_dl_name_match_p): Make MAP parameter const.
	* sysdeps/generic/ldsodefs.h: Adjust prototype.
