# lfs/ Per-architecture copies of the hosted `starforth` binary. The hosted `Makefile` copies the freshly built binary here as its last build step (`cp $(BINARY) lfs/$(ARCH_DIR)/starforth`), separate from `build///`, which is the working build-output tree. - `amd64/starforth`, `arm64/starforth`, `riscv64/starforth` — one binary per architecture, rebuilt whenever that architecture's hosted build runs.
