* elf/dl-lookup.c (_dl_lookup_symbol): Take new arg RELOC_ADDR and
don't allow a defn resolving to that address.
* elf/link.h: Update prototype and comment.
* elf/dl-runtime.c (fixup): Define local `resolve' function and pass
it to elf_machine_relplt.
* elf/dl-reloc.c (_dl_relocate_object: resolve): Take new arg
RELOC_ADDR and pass it through to _dl_lookup_symbol.
* elf/do-rel.h (elf_dynamic_do_rel): Pass RESOLVE to elf_machine_rel
instead of calling it ourselves and passing its results.
(elf_dynamic_do_rel): RESOLVE fn takes new arg RELOC_ADDR.
* elf/rtld.c (dl_main): Pass 0 for RELOC_ADDR to _dl_lookup_symbol.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Remove SYM_LOADADDR
arg. Add RESOLVE function ptr arg. Call *RESOLVE as necessary.
* sysdeps/m68k/dl-machine.h (elf_machine_rela): Likewise.
* sysdeps/stub/dl-machine.h: Likewise.
* csu/initfini.c (_fini): Add extern decl for i_am_not_a_leaf.
* elf/dlfcn.h (dl_open_mode): Enumerated type removed.
(RTLD_LAZY, RTLD_NOW): Define these as macros instead.
(RTLD_GLOBAL): New macro.
(dlopen): Take arg of type int instead of dl_open_mode.
* elf/dlopen.c: Likewise.
* math/math.h (_Mldbl): New macro, either produces L suffix or not.
(M_*): Use it for these constants.

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.
