Why are you compiling on ARM with only 4GB RAM? Wouldn't it make more sense to cross compile from a machine with more resources, if you cared about build speed?

Why are you compiling on ARM with only 4GB RAM? Wouldn't it make more sense to cross compile from a machine with more resources, if you cared about build speed? (maybe there's a good reason not to do that, idk) If it's crapping out when you give it -j8, that seems to strongly suggest you're running into limited resources somewhere. I'm no expert in the intricacies of parallel builds, but as far as I know you can still have dependencies between targets that will limit parallelism.
