I just looked at the gcc docs and it turns out there's a syntax for 
initializing arrays that lets you explicitly specify indexes:
	int a[6] = { [4] 29, [2] = 15 };

So, for now, write your own execute_syscall.  I'll rework it into something 
which has a syscall table that says things like:
	{ [__NR_exit] sys_exit,
	  [__NR_fork] sys_fork,
	  ...
          ARCH_SYSCALLS }

And the i386 ARCH_SYSCALLS would have 
	[__NR_vm86] sys_ni,
	...
and all the others that don't exist on ppc.

And yours would have whatever things are different on ppc.
