No, I know what *extra* flags are needed for that source, not what those
flags will be added to. For instance I know I need to disable a warning
because of an unavoidable local false positive, but not to enable debug

Yes, per my previous email I'm doing that already. as the second to last

loop over all the targets (top level and below) for each build flavor.

Yes, as I've mentioned several times, the idea of this is to get closer to
plain SConscripts and remove our extra layers. I'm trying to figure out how
to do that.
