I think the problem was that -DCMAKE_BUILD_TYPE=Release would already
add some compiler flags like "-O3 -DNDEBUG", but we specify our own
flags in CFLAGS and CXXFLAGS and we end up with both on the command line.
Sounds like it should actually be -DCMAKE_BUILD_TYPE=None in the
cmake-1.1 port group and the wanted compiler flags can then be passed
via CFLAGS and CXXFLAGS in the environment (as we already do).

As "None" is generated by default by CMake, it should work with all
projects.
