Update.
* elf/rtld.c (_dl_start_final): Allocate TLS and initialize
thread-pointer as soon as possible.
* sysdeps/generic/ldsodefs.h: Include <tls.h>. Define first TLS
elements in rtld_global.
* sysdeps/generic/tls.h: New file.
* elf/Makefile (distribute): Add tls.h.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Add support for TLS
relocations. Not complete yet.
* resolv/resolv.h: Allow user to define __need_res_state and only
define __res_start structure then.
* include/resolv.h: Only declare functions if _RESOLV_H_ is defined.
