See the reply from Arnout and Dagg for gcc 4.9:
I'm not sure that the odroidc2 defconfig is able to build with gcc >= 4.9 since
it's stuck at kernel odroidc2-3.14.y and uboot odroidc2-v2015.01.
Dagg, what do we do for this board?

Ok, sometime I forgot to add -N when generating a patch series for a package...
