Update Makefile documentation

Follow-up to previous commit. Update the documentation for the user when using `make`,
to show the preferred bmi2 compile in the advanced examples section.

Note: I made a mistake in the previous commit comment, the documentation is shown when
using `make` or `make help`, not `make --help`.

No functional change
