The current code has continued to work on OpenBSD, since it has been using syscall(2) via libc. However, the system call numbers are still hardcoded in golang.org/x/sys/unix. Various system call changes have been made in OpenBSD, resulting in changes to the system call numbers and arguments, which now fail when this package is used. Switch to calling various system calls directly via libc, rather than calling via libc using syscall(2).
