* 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.
