I made a comparison with and without -g (with ccache disabled for that test). rockbox.sansa is identical in both cases Without -g: make -j8 293,60s user 17,61s system 690% cpu 45,075 total $ du -chs . 34M . With -g: make -j8 321,22s user 19,88s system 688% cpu 49,556 total $ du -chs . 99M . I think it's a good idea. If disk usage increase on the clients is too much we can add a configure option to remove -g. Like --debug --no-debug, defaults to --debug.
