I prefer to have a dedicated directory to store all the .dwo files. As dblaikie  said, all the .dwo files are temporary files. In addition, in order to differentiate the .dwo files generated by different link stage with the same .o, we need to add
some suffixes to the .dwo file. So for a file a.o, we may need to generate a .dwo named a._${number}_${random_string}.dwo, which is not neat. Furthermore, we need to dealing with archive files. In this case, we may need to generate
multiple .dwo files for a single archive files.
