The arch ioctl tables are doing this:

	struct foo ioctl_start[] = {
		...
	};
	struct foo ioctl_end[0];

and fs/compat.c expects that the table lies between &ioctl_end and
&ioctl_start.

Problem is, gcc-3.3 puts ioctl_end into bss, even if it is initialised.  It
doesn't work.

So we do away with the ioctl_end thing and add

	int ioctl_table_length = ARRAY_SIZE(ioctl_start);

to each architecture.
