So this check does not work at all.  I could never get the -z to show that the arg was not defined.
Even if I defined fdtfile=\0 the variable indicates that is is still undefined.

And I cannot add in the "" because the compiler bonks thinking the macro line is completed.

So what I am going to do is pull this out of this patch completely because this has no impact on the intent of the patch.
I will then go ahead and fix the omap4_common, omap5_common and the am335 common in a separate patch.

Thoughts?
