currently there is clutter 1.4 and clutter 1.6 which both use the 
clutter.inc. and yes, It is also fine to use duplicate bbappend to 
append clutter 1.4 and clutter 1.6 respectively. But if clutter.inc can 
be appended, then it will reduce the duplicate code. Also inc file 
append has another benefit, when clutter 1.8 is out in the future, the 
BSP append code don't need any change.
