Instead of relying on syscall.Syscall, always reach into the syscall package to call the appropriate functions on Unix systems. We were already doing this on Darwin and AIX. We also have to do this on OpenBSD, and it's simpler to do it on Linux 386 and s390x. Rather than sometimes reach into syscall and sometimes not, just always reach in.
