Only openrisc has no vfork.S.
So new architectures have no vfork anymore?

If there is no __NR_vfork in unistd.h, vfork.S is empty.
eg nds32 vfork.S:
#ifdef __NR_vfork
...
#endif
eg arc vfork.S:
Are you sure it could compile with the linux-4.16-rc5? There is no
__NR_vfork at all.
For csky, we don't have historical burdens, we are new born.
