package/protobuf: needs gcc >= 4.5

Browse Source 
Even with an upstream patch from protobuf v3.3 [1], the build fail with another issue:

In file included from google/protobuf/dynamic_message.cc:80:
./google/protobuf/map_field.h: In member function 'void google::protobuf::internal::MapField<Key, T, key_wire_type, value_wire_type, default_enum_value>::Swap(google::protobuf::internal::MapFieldLite<Key, T, kKeyFieldType, kValueFieldType, default_enum_value>*)':
./google/protobuf/map_field.h:139: error: object missing in reference to 'google::protobuf::internal::MapFieldBase::repeated_field_'
./google/protobuf/map_field_inl.h:342: error: from this location
./google/protobuf/map_field.h:150: error: object missing in reference to 'google::protobuf::internal::MapFieldBase::state_'
./google/protobuf/map_field_inl.h:344: error: from this location

Add a dependency on gcc >= 4.5.
