That turns out to be fairly easy:

#undef __SYSCALL
#define __SYSCALL(nr, call) [nr] = (call),

#ifndef __tilegx__
#define sys_fadvise64 sys32_fadvise64
#define sys_fadvise64_64 sys32_fadvise64_64
#define sys_readahead sys32_readahead
#endif

void *sys_call_table[__NR_syscalls] = {
	[0 ... __NR_syscalls-1] = sys_ni_syscall,
#include <asm/unistd.h>
};
