It also changes the expected value for newer ports from 0x100 to 0x0, aligning with Linux UAPI. The idea is to simplify the Linux 5.1 wire-up of sysvipc syscalls for some 32-bit ABI, which expected __IPC_64 to be 0x0 (thus tying its value to minimum supported kernel version). There is no semantic change expected on any port.

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 5.1.2 kernel with --enable-kernel=5.1. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALLS): Only undefine if [__LINUX_KERNEL_VERSION < 0x050100].
