[boost] "/usr/bin/objcopy" --set-section-flags .debug_str=contents, debug

just curious. Why do debug builds of boost on gcc use this? What does it mean? I'm just wondering. I've never seen it needed for any other build. g++ -g is all that I've ever seen used to build a debug version of anything. "/usr/bin/objcopy" --set-section-flags .debug_str=contents,debug
