Change the loop to rename the generated assembly
stub __seek and treat it like any other system call
(no special code; just the name change).

Then add this C function:

	int _seek(vlong*, int, vlong, int);

	vlong
	seek(int fd, vlong off, int whence)
	{
		vlong ret;
		if(_seek(&ret, fd, off, whence) == -1)
			return -1;
		return ret;
	}

You should never ask "how do I write this in assembly?"
You should ask "how do I *not* write this in assembly?"

P. S.  You might also change gcc not to prefix all the
C functions with underscores.  (I'm sure there's an option.)
Real systems gave that up a long time ago.
