Right now you are building two, basically duplicate images: Cubietruck 
and BananaPi.  All that is different between them is the uboot.

So one enforcing image takes longer than building two (or more as you 
add boards like Cubieboard2, Wandboard, etc.)?

Thus, exempt for RPi2, you build one image with selinux enforcing and 
you  have the centos-arm-installer script have the option to switch to 
permissive.
