This should (imnsho, at least),
	1 - Add a cond_syscall for sys_sysfs to sys_ni.c
	2 - Use a CONFIG_EMBEDDED dependent option that defaults on,
	    possibly depend on BLACKFIN if you really want to.

Adding this junk to every arch header is, in my opinion, completely
unacceptable just because blackfin wants to be different.
