	* Makefile (subdirs): Added db.

	* resolv/Makefile (routines): Add res_data.
	* resolv/res_data.c, resolv/res_debug.c, resolv/resolv.h:
	Updated from BIND 4.9.3 final release.

	* elf/dynamic-link.h (elf_get_dynamic_info): Handle
	processor-specific tags.
	(ELF_DYNAMIC_DO_REL, ELF_DYNAMIC_DO_RELA): Handle absent DT_PLTREL tag.

	* elf/elf.h (DT_MIPS_NUM, DT_PROCNUM): New macros.
	* elf/link.h (struct link_map): Extend `l_info' by DT_PROCNUM.

	* sysdeps/i386/dl-machine.h (elf_machine_runtime_setup): Take new
	arg LAZY.  Only do our work if LAZY and there is a DT_JMPREL record.
	* elf/dl-reloc.c (_dl_relocate_object): Call
	elf_machine_runtime_setup unconditionally, and pass it LAZY flag.

	* elf/dl-load.c: Fixed ELFMAG check to work for either byte order.
	Align end of load segment only to page size, not to segment alignment.
