Update.
* elf/rtld.c (_dl_start): Fill TLS values in link map for rtld.
* include/link.h (struct link_map): Add various members for TLS
information.
* sysdeps/generic/ldsodefs.h (struct rtld_global): Remove
_rtld_tlsoffset, add _dl_initimage_list.
* sysdeps/i386/dl-lookupcfg.h: New file.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Implement missing
TLS relocation. When using TLS we now use RESOLVE_MAP.
(elf_machine_rela): Use RESOLVE_MAP instead of RESOLVE_MAP if TLS
is used.
* sysdeps/generic/dl-cache.c (_dl_cache_libcmp): Mark as possibly
unused.
