functionality and speed improvements over early 0.9.x series
- Build with GCC 4.6+ by default, as it provides better OpenMP support, but
allow to use system compiler for a time being
- Explicitly link darktable executable to libstdc++, to workaround problem
with CMake, which strips any RPATH from libdarktable.so, which in turn
results in wrong libstdc++ being picked when using GCC from ports
- Use ONLY_FOR_ARCHS (with reason) instead of BROKEN statement
