Not just a change in the code, sometimes just a different payload (ADLO vs.
FILO), but it's the same dependency issue.

Given that you recommend _always_ removing the BUILDDIR, I think the best
thing to do is to put the 'rm -rf BUILDDIR' into buildtarget.  There's no
reason to make it two steps.  It makes sense that when you run buildtarget
that it takes care of the details to make it build.

Is that on the wake?
