	* sysdeps/s390/Versions [GLIBC_2.3] (ld): Export __tls_get_offset.
	* sysdeps/s390/dl-tls.h: New file.
	* sysdeps/s390/libc-tls.c: New file.
	* sysdeps/s390/s390-32/dl-machine.h (elf_machine_type_class): Add TLS
	relocs for class PLT.
	(elf_machine_rela): Handle TLS relocs.
	* sysdeps/s390/s390-64/dl-machine.h: Likewise.
	* sysdeps/s390/s390-32/elf/configure.in: Add TLS check.
	* sysdeps/s390/s390-64/elf/configure.in: Likewise.
	* sysdeps/unix/sysv/linux/s390/s390-32/clone.S: Add support for
	CLONE_CHILD_*TID flags.
	* sysdeps/unix/sysv/linux/s390/s390-64/clone.S: Likewise.
	* sysdeps/unix/sysv/linux/s390/s390-64/mmap.S: Use branch with 32
	bit offset.

	* sysdeps/unix/sysv/linux/s390/s390-64/syscall.S: Likewise.
	* sysdeps/unix/sysv/linux/s390/s390-32/sysdep.S (__syscall_error):
	Support USE___THREAD. Define RTLD_PRIVATE_ERRNO variant.
	* sysdeps/unix/sysv/linux/s390/s390-64/sysdep.S (__syscall_error):
	Likewise.
	* sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h:
	(SYSCALL_ERROR_LABEL): Move define next to SYSCALL_ERROR_HANDLER.
	(SYSCALL_ERROR_HANDLER): Add USE___THREAD and RTLD_PRIVATE_ERRNO
	variants.
	* sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h:
	(SYSCALL_ERROR_LABEL): Move define next to SYSCALL_ERROR_HANDLER. Use
	direct branch to syscall_error for !PIC and PIC && !_LIBC_REENTRANT.
	(SYSCALL_ERROR_HANDLER): Add USE___THREAD and RTLD_PRIVATE_ERRNO
	variants.
