I think this change actually doesn't do anything: __NR_fork was still being defined either way, and on my machine fork() in <unistd.h> comes from libc.
This just moves to the standard mechanism for defining syscalls that aren't implemented instead, which has the side-effect of no longer having an #ifdef CONFIG_* in a user-visible header.
