CPU artifacts — built on every platform.

GGML_METAL_A =

Metal artifacts — built on Darwin only. The Metal libggml.a is a side-effect of ‘make setup` on Darwin; the Metal tinynn shim is a separate target that install must request explicitly, else example_inference_metal can’t link on a fresh Mac build.
