./b.sh --armhf builds headless and the unit tests for 32-bit ARM, which run under qemu-arm the way the loongarch64 and riscv64 builds do. setup-cross.sh learns the target (it also needs an EGL stub), and the docs cover setting it up without root. hash/hash dies with a bus error under qemu-arm on every CPU core, so it goes in a known-failures list for the target.
