The system call tables and the compat wrapper are all manually created.
If we manage to get the prototypes for the system calls in a parseable
format at least the compat wrappers could be auto-generated. I see two
pitfalls: 1) some compat system calls are directly wired to the system
call table while others need the compat_wrapper detour, 2) override of
system calls with "meta" system calls like sys_socket or sys_ipc.
