* elf/dl-lookup.c (_dl_debug_bindings): Print TLS lookups always.
* elf/elf.h (R_386_TLS_TPOFF, R_386_TLS_IE, R_386_TLS_GOTIE,
R_386_TLS_LE): Define.
(R_386_TLS_IE_32, R_386_TLS_LE_32, R_386_TLS_TPOFF32): Update
comments.
* sysdeps/i386/dl-machine.h (elf_machine_type_class): Return
ELF_RTYPE_CLASS_PLT for R_386_TLS_TPOFF.
(elf_machine_rel): Handle R_386_TLS_TPOFF.
(elf_machine_rela): Likewise.
Remove unnecessary RTLD_BOOTSTRAP #ifdefs.
