Log:
  devel/arachne-pnr: fix build with GCC-based architectures
  
  Building with GCC9 fails with:
  src/util.hh: In instantiation of ‘std::set<typename M::key_type> keys(const M&) [with M = std::map<CBit, bool>; typename M::key_type = CBit]’:
  src/chipdb.cc:73:23:   required from here
  src/util.hh:191:24: error: moving a local object in a return statement prevents copy elision [-Werror=pessimizing-move]
    191 |   return std::move(keys);
        |                        ^
  src/util.hh:191:24: note: remove ‘std::move’ call
  
  As reported at https://github.com/YosysHQ/arachne-pnr/issues/134
  
  Add -Wno-error=pessimizing-move to CFLAGS for GCC build.
