	* sysdeps/unix/sysv/linux/ia64/sysdep.h (BREAK_INSN_1, BREAK_INSN,
	ASM_OUTARGS_0, ASM_OUTARGS_1, ASM_OUTARGS_2, ASM_OUTARGS_3,
	ASM_OUTARGS_4, ASM_OUTARGS_5, ASM_OUTARGS_6): Define.
	(INTERNAL_SYSCALL, INLINE_SYSCALL): Use it.  Make syscall arguments
	clobbered by the syscall.
	(ASM_ARGS_1, ASM_ARGS_2, ASM_ARGS_3, ASM_ARGS_4, ASM_ARGS_5,
	ASM_ARGS_6): Change constraints from r to index of corresponding
	output register.
	* sysdeps/unix/sysv/linux/ia64/clone2.S (__clone2): Swap
	ptid and ctid to match kernel.
	* sysdeps/unix/sysv/linux/ia64/system.c (FORK): Likewise.

	* sysdeps/powerpc/powerpc64/elf/configure.in: Remove
