TLS support for libpthread, Mach/Hurd (x86).
* Makefile (CFLAGS): Define ENABLE_TLS.
* pthread/pt-create.c (__pthread_create_internal) [ENABLE_TLS]: Call
into glibc to allocate static TLS block.
* pthread/pt-exit.c (pthread_exit) [ENABLE_TLS]: Call into glibc to
deallocate static TLS block.
* pthread/pt-internal.h [ENABLE_TLS] (tcbhead_t): New structure; as in
glibc.
(__pthread) [ENABLE_TLS]: Add TCB member.
[ENABLE_TLS] (_dl_allocate_tls, _dl_deallocate_tls): Declare; from
glibc.
* sysdeps/mach/hurd/pt-sysdep.h (__thread_set_pcsp): Rename to
__thread_set_pcsptp. Add SET_TP and TP parameters. Change all
callers.
* sysdeps/mach/hurd/i386/pt-machdep.c (__thread_set_pcsptp): Imlement
TLS support.
* sysdeps/mach/hurd/i386/pt-setup.c (__pthread_setup): Likewise.
