The __IPC64 flags is meant to be used to enable the new sysv struct
format when the architectures supports it (ARCH_WANT_IPC_PARSE_VERSION
config flag on Linux kernel).

This currently issue only affects alpha.

	* sysdeps/unix/sysv/linux/msgctl.c (__old_msgctl): Remove __IPC_64
	usage.

Doesn't this need a bug number (with a description of the impact in the
bug, if possible).

Thanks,
