[COMMITTED 2.26] ia64: Add ipc_priv.h header to set __IPC_64 to zero

[Aurelien Jarno]

From: James Clarke <jrtc27@jrtc27.com>

When running strace, IPC_64 was set in the command, but ia64 is
an architecture where CONFIG_ARCH_WANT_IPC_PARSE_VERSION *isn't* set
in the kernel, so ipc_parse_version just returns IPC_64 without
clearing the IPC_64 bit in the command.

	* sysdeps/unix/sysv/linux/ia64/ipc_priv.h: New file defining
	__IPC_64 to 0 to avoid IPC_64 being set.

Signed-off-by: James Clarke <jrtc27@jrtc27.com>

(cherry picked from commit 89bd8016b30e504829bea48c4cd556769abfcf3a)
