If a deep dependency fails with "no way to make", only a direct dependency of the main goal is mentioned

[rulatir]

Makefile:

foo: bar
	cp $< > $@

bar: vex
	cp $< > $@

vex: irk
	cp $< > $@

irk: baz
	cp $< > $@

baz: naz.in # typo, should be baz.in (what matters is that naz.in doesn't exist)
	cp $< > $@

GNU Make output:

make: *** No rule to make target 'naz.in', needed by 'baz'.  Stop.

biomake -H output:

While building foo: No way to build bar, needed by foo

The error message only mentions a cascade-failing direct dependency of the main goal instead of pointing at the real error like GNU Make does.

The problem can be worked around by attempting to make the failing dependency to discover the next node on the failing path, and so on until the culprit is found. But this workaround shouldn't be necessary.
