This needs to be automatic, so that it builds the 32-bit version on 32-bit hosts, 64-bit version on 64-bit hosts. See here for my attempt. I suspect it just needs your bits_per_long thing brought in, but in any case I hope it gives you inspiration. https://patchwork.ozlabs.org/project/uboot/patch/20220123195514.3152022-4-...@chromium.org/ Basically we should be able to build sandbox on any platform and it should just work, without manual configuration.
