[1/5] sysvipc: Fix compat msgctl
Commit Message
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,
