This fails in cases where the makefile emits something to stderr when
setting a variable, which can happen even for non-existing rules.
Makefiles with global pattern rules (as used with dh) are also

A more robust method would be to populate unique-tmp-1 by running
debian/rules this-dummy-target-better-not-really-exist

Or, make could be patched to have a mode where it generates stable,
machine-parseable error and status message codes. Then just look for
the one that corresponds to "*** No rule to make target" or the one that
indicates a rule has been run.
