make for Banglejs problem with bootloader

Ahh - so NO_COMPILE=1 is that something you'd added for your builds?

I guess ideally if you want something other than a binary you'd have a build target, so ... make myfiles

But in this case it's because normally nRF52 code needs a bootloader to create a usable hex file. If you add DFU_UPDATE_BUILD=1 to it, it'll try and create an update package which doesn't require the bootloader
