It's the non-default ones that needs to be shown. I agree that they don't need to be in the report, but just having them in a variable (e.g. system-configuration-options) would make it easier for users to see what the default switches are. For example, I would have compared system-configuration-options between the slow and fast builds and noticed that the fast build had '-O2' while the slow one didn't, and this report wouldn't have been filed.
