Linux 5.1 adds missing SySV IPC syscalls to the syscall table for
remanining one that still uses the ipc syscall on glibc (m68k, mips-o32,
powerpc, s390, sh, and sparc32). However the newly added direct ipc
syscall are different than the old ones:
1. They do not expect IPC_64, meaning __IPC_64 should be set to zero
when new syscalls are used. And new syscalls can not be used
for compat functions like __old_semctl (to emulated old sysvipc it
requires to use the old __NR_ipc syscall without __IPC_64).
Thus IPC_64 is redefined for newer kernels on affected ABIs.
2. semtimedop and semop does not exist on 32-bit ABIs (only
semtimedop_time64 is supplied). The provided syscall wrappers only
uses the wire-up syscall if __NR_semtimedop and __NR_semop are
also defined.
Checked on x86_64-linux-gnu and i686-linux-gnu on both a 4.15 kernel
configure with default options and sysvipc tests on a 5.3.0 kernel with
--enable-kernel=5.1.
