SIGBUS on crochet for rpi3

[Matt Dube]

Hi, I'm not sure if I'm doing something obviously wrong but I get the
following when I try to build the image for rpi3 with crochet.

I've only ever seen SIGBUS on compilation on a parallel fs when a node
rebuilds an object file while another one is trying to use it so I'm not
sure what's causing this.

Anyone has seen this?

Thanks
-Matt
