So are your sure '${B}/arch/arm/boot/dts/overlays' isn't needed during
compile? I tried with changing above from append to prepand instead and
then it worked fine for me (when building 3.18 kernel). (from
log.do_compile, complete log can be found at:

Hmm Ok, might be some "pebcak" from my side, since I was using an
old sstate, but according to my history I did 'cleanall' before I got
the problem. But will re-try this on a completely new build without any
old savings (it will take some time to test however..). What struck me
was that the failure occurred in do_compile (from what I can tell the
failure in my logs occur before your _append had been able to do
anything about it?). I will analyse the run.do_compile if the failure
occurs again and see if that make any sense. I will let you know if the
problem occurs again. But since both you and Herve haven't seen any
problem I guess it's something I'm doing wrong.. 

BR, Petter
