My initial patches does have generated-y += unistd_32.h instead of
generic-y += unistd_32.h.
If I remember someone pointed out that this implementation doesn't
look good. So I
replaced to generic-y += unistd_32.h.

Sure, I'll change to generated-y += unistd_32.h instead of generic-y
+= unistd_32.h.

Max, this looks ok. right?

Thanks
Firoz
