* elf/dl-lookup.c (_dl_lookup_symbol): Arg NOSELF renamed to NOPLT.
Reject SHN_UNDEF defns iff NOPLT is nonzero. * elf/link.h (_dl_lookup_symbol): Update prototype and comment. * elf/dl-runtime.c (fixup): Pass 1 to _dl_lookup_symbol for NOPLT. * elf/dlsym.c (dlsym): Pass 0. * elf/rtld.c (dl_main): Likewise. * elf/dl-reloc.c (_dl_relocate_object: resolve): Second arg R_OFFSET replaced with NOPLT flag. Pass it through to _dl_lookup_symbol. * elf/do-rel.h (elf_dynamic_do_rel): Update prototype of RESOLVE arg. Pass `elf_machine_pltrel_p (R->r_type)' result as NOPLT flag value. * sysdeps/i386/dl-machine.h (elf_machine_pltrel_p): New macro. * sysdeps/m68k/dl-machine.h (elf_machine_pltrel_p): Likewise. * sysdeps/stub/dl-machine.h (elf_machine_pltrel_p): Likewise.
