Makefile_1 can capture the exit code of '$(MAKE) Makefile_2',
and vary its subsequent behavior according to the value returned.
But 'make' has only three possible exit codes, and only two that
would probably be useful to you. Alternatively, you could redirect
the submakefile's output to a file and parse that upstream.

You may need to write '-' before commands, or use '-k', to
prevent 'make' from stopping at the first error.
