[Dune] dunecontrol not faster with set DUNE_CONTROL_PATH

[Christoph Grüninger]

Hi Christian and Markus,
I wrote an additional section for the buildsystem documentation and 
finally tested what I wrote. I encountered the same problem as Markus, 
no speedup.
Is this feature maybe broken? At least the value of the environment 
variable is honored because if I place an empty dune.module file in a 
sub-sub-directory it is only found without the opts file.
