COMP: downgrade error to warning when building run-time post-pro

- although the build is not 100% complete, it is only the run-time
  post-processing with VTK that is affected.

- improve robustness and warning messages

COMP: adjust build order (solvers, utilities)

- as per http://bugs.openfoam.org/view.php?id=2116
