I would say there is some object files left hanging around in
the patch that should have been removed. My build machine is
an x86-64, so I would say my patch generation script hasn't
cleaned out config/kconfig/zconf.tab.o

Clean out the objects in there after patching, so do:

     rm config/kconfig/*.o
     rm config/kconfig/conf

I expect you should be able to build after that.

Regards
Greg
