It is building linux-yocto 4.1. I have attached the compilation log, in 
case that helps.

What I am doing is simply building a vexpress-qemu machine with poky's 
master, so it should be quite straightforward to reproduce.

In particular, I am following our projects guide for creating a Mender 
build at 
https://github.com/mendersoftware/meta-mender/blob/master/README.md, but 
I don't think it reaches the Mender-specific layers.

Thanks for the help and let me know if there's anything else you need.
