In that story, commands/Makefile would make commands/built-in.a and
various commands/foo.o. The toplevel makefile would pass "make -C
commands" a long list of targets to build, presumably deduced from
$(MAKECMDGOALS). Not pleasant, I agree.

It could be pretty simple by maintaining a $(prefix_) variable
representing the path from the cwd to the directory containing the
makefile. Might try it out.

That sounds best to me in the short term, too.

Yes, reasonable.
