i was unaware that PathFormat can fail in this way :(

in general you are right, configure clearly shouldn't create empty paths
in case of error, so i've changed the PathFormat on master to report errors.

but in this case there shouldn't be a warning, because it's legitimate
that the workdir/$INPATH and solver/ subdirs don't exist at configure
time, and we already check that the $with-solver-and-workdir-root
exists; so i've fixed the PathFormat invocation on master too. please
try again.
