* elf/dl-load.c (_dl_map_object): Add MAP_INHERIT flag in mmap
from zero fill. * elf/dl-lookup.c (_dl_lookup_symbol): Take new flag arg NOSELF; if nonzero, don't let *REF satisfy the reference itself. * elf/link.h (_dl_lookup_symbol): Add new arg NOSELF in decl. * sysdeps/i386/dl-runtime.c (_dl_runtime_resolve): Pass new arg to _dl_lookup_symbol. * elf/do-rel.h (elf_dynamic_do_rel): Pass new second arg of R->r_offset to RESOLVE callback. * elf/dl-reloc.c (_dl_relocate_object: resolve): Don't let *REF satisfy the reference itself if its value equals the reloc's offset. * elf/rtld.c (dl_main): Write a newline in fatal msg. * Makerules (lib%.so: lib%_pic.a): Pass $(LDFLAGS.so).
