Sorry, I see that I wasn't clear earlier.  Not all phony targets have
the problem.  For example, the following works fine:

.PHONY: all

all: foo

foo: /etc/motd
        cat /etc/motd >$@

The problem occurs only when a phony target has a nonempty action,
and when "make -q" depends on the phony target.

If you can program a sanity check this way:


where SANITY expands to the empty string if the check succeeds,
and to 'false' if it fails, then 'make -q' should work.  This is
true regardless of whether 'sanity' is phony.
