Add sparc64 TLS and NPTL support.

Browse Source 
* elf/tls-macros.h: Add Sparc64 defines.
	* sysdeps/sparc/sparc64/dl-machine.h (sparc64_fixup_plt): Mark as
	always_inline.
	(elf_machine_fixup_plt): Likewise.
	(elf_machine_rela): Handle TLS relocations.
	(elf_machine_type_cleaa): Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h
	(SYSCALL_ERROR_HANDLER_ENTRY): Use sethi/or for GOT reloc.
	It does not always fit in R_SPARC_GOT13 when building -fPIC.
	Also, add TLS handling.
	* sysdeps/unix/sysv/linux/configure.in (arch_minimum_kernel):
	Increase it to 2.4.21 for sparc64.
	* sysdeps/unix/sysv/linux/sparc/sparc32/clone.S: NULL terminate
	backtrace by zero'ing out %fp.  Store away flags, func_ptr,
	and func_arg in global registers not local registers.
	* sysdeps/unix/sysv/linux/sparc/sparc64/clone.S: Handle PTID, TLS,
	and CTID arguments properly.  Add RESET_PID handling.
	* sysdeps/unix/sysv/linux/sparc/sparc64/pause.c: Rework so that we
	do not invoke __sigprocmask().  We can always assume rt signals
	are present on sparc64, so just do an inline syscall.

	* sysdeps/sparc/sparc64/dl-machine.h: Add dl_machine_h multiple
	inclusion guard for the first half of the header.
	(elf_machine_type_class, ELF_MACHINE_JMP_SLOT, ELF_MACHINE_NO_REL,
	ELF_MACHINE_PLTREL_OVERLAP, elf_machine_runtime_setup,
	elf_machine_relplt, DL_STACK_END, RTLD_START): Move into the
	#ifndef dl_machine_h guarded part of the header.
