Harden the cross-compile target re-export against `set -e`: the prior `[ -n "$x" ] && export ...` form returns non-zero when the var is empty (the common native-build case). Empirically bash exempts it from errexit, but the explicit `if` form is unambiguous across shells. Both native (Mach-O arm64) and cross (ELF linux/amd64) builds verified via ./scripts/run_task.sh build. Co-authored-by: Hanzo Dev <dev@hanzo.ai>
