Subject: [PATCH] [cmake] Make sure that string(REPACE always has 4 arguments.

This was missing proper quoting for the case that dune-common_CXX_FLAGS
is empty.

Error I got was:
```
-- Version 2.10.0 of dune-common from /home/mblatt/src/dune/opm-master/dune-common/opm-parallel
CMake Error at CMakeLists.txt:369 (string):
  string sub-command REPLACE requires at least four arguments.

-- Configuring incomplete, errors occurred!
```
