* 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.
