@Michael, I believe this is probably due to a architecture miss match on our cloud builders. looking at the buildme script, it looks for an arch of either armv6l or armv7l when compiling natively, unfortunately, our builders currently don’t identify with that arch. I know @cameron was looking into this.
One work around would be to force the build type to be a crosscompilation somehow. Another possibility is to use the emulated build servers, which should have the correct arch, but are a bit slower. You can do that by doing a git push resin master:resin-emulated
