I still don't understand why you need a separate syscall table.  You
should really be able to run on an unmodified amd64 kernel, in 64 bit
mode.  This would imply that tools like strace don't need any porting
at all (you could just use the amd64 version), and even GDB would
mostly worked unchanged.
