It will say this if you defined an explicit rule, since then make knows
that _THIS_ rule should work, and if a prerequisite can't be created it
can tell you about it.

If you defined an implicit rule then make can't know that _this_
implicit rule should have matched, out of all the different implicit
rules that might have matched, so printing an error about not being able
to create a particular prerequisite is not appropriate.

The debug output _WOULD_ tell you that make considered this rule, and it
would even tell you that it tried to find a way to build the
prerequisite and couldn't.
