if accepted please forward there.

- binutils 2.27 creates empty modules without a symtab.

+Accept empty modules
+
+For the Xen platform the all_video.mod module is empty.
+With old binutils the .symtab section remained (containing
+only section symbols), so the check didn't trigger, but starting
+with binutils 2.27 not even a .symtab remains.  As there are
+also no relocations that's no problem (and that is checked
+independendly).
