[dune-pdelab] Issues in 2.0-rc1

[Christoph Grüninger]

Hi Steffen,
thanks for preparing a release candidate. I had some issues 
regarding
make headercheck and with CMake in make check. I have not yet 
found
the time to prepare proper patches. I hope I can do so until 
the end
of the week.
I attached was I changed so far.

Bye
Christoph
