Do for all archs what I did for x86; and broken is checked during template parsing time, not during `do_build`. This is "better" but still breaks builds; you need something in an environment file to set `broken` so XBPS doesn't error out. To avoid duplicating the logic, could create `XBPS_ZIG_ABI` ... and use those instead of local variables.
