We do not directly bbappend recipes to maintain yoctoproject compatible 
status.  Please check other bbappends in meta-arago for examples on how 
to do this properly.  For example: 
meta-arago-distro/recipes-multimedia/libtiff/tiff_%.bbappend


This same comment applies to the other patches where you add bbappend 
files as well.
