Additional information:
"Only" PowerPC executables and kernels are affected. You find GNU_STACK in
the kernels of all PPC ports.

So there's just something which has been forgotten in the PowerPC tools?

In PPC object files there is also this ".note.GNU-stack" section, which is
missing for other architectures. From a short glance at the ld sources I
think that the GNU_STACK segment is automatically created when such a
section was found in any object file.

But I see no option to suppress ".note.GNU-stack" in objects...
