Reference the Makefile instead of duplicating its behavior.

This paragraph restates the host-selection and forwarding contract owned by mobile/Makefile. Replace those mechanics with a reference to the Makefile to prevent the documentation from drifting.

As per coding guidelines, “docs […] must bind/import/project the canonical owner instead of restating it (No Mirrors).”

Update the `mobile/README.md` paragraph to reference `mobile/Makefile` as the
canonical source for remote build behavior instead of describing host selection,
goal forwarding, checkout mirroring, or output location. Preserve only the
guidance needed to direct readers to the Makefile.
