This change is definitely safer using and older kernel that doesn't have a
generated bounds.h .. but your tree is out of date. This should be on
top of:

     kernel.bbclass: fix external module building

     Without that fix we have the following while compiling compat-wireless.
       include/linux/mmzone.h:18:30: fatal error: generated/bounds.h: No 
such file or directory

     Note that the compat-wireless recipe will be added in another commit.

     make -C $kerneldir _mrproper_scripts deleted this file along with
     other things so we resurrect it with this patch.
