We currently use the tools-all option, details below, to build the
tools, which broken in 2018.11 on non arm/x86 platforms due to the
sandbox dep being added in there. I'm happy to adjust as necessary to
fix that but I'm not sure the difference between tools-all vs the
above.

make CROSS_COMPILE="" defconfig V=1 O=builds/
make CROSS_COMPILE="" tools-all V=1 O=builds/
