It tends to change with the Linux kernel version, as architectures change 
how they handle their syscall tables.  (Hopefully ongoing changes to unify 
the machinery more between different architectures will make such checks 
easier for future kernel versions - while not helping when it's past 
syscalls you're looking at.)
