I take it that you anticipate the fuzz programs in the future all
be named fuzz-$(blah), whose source is fuzz-$(blah).o (even though
we may grow some common code that may be linked with them, which can
be done by tweaking the rule for the $(FUZZ_PROGRAMS) target).  Am I
reading you correctly?  Would fuzz-{clean,objs,compile} risk squatting
on nicer names we may want to use for $(blah) down the line?

Is the expected usage pattern to know a single fuzz-* program the
builder wants to build, to run "make fuzz-pack-headers"?  If not, it
also would be a good idea to have something like

    fuzz-build-all:: $(FUZZ_PROGRAMS)
    .PHONY: fuzz-build-all


Also, in the final version we unleash to general developer audience,
we'd want to support "make V=1" (and "make" that is "$(QUIET)").
