When you say "ran a few builds", was this with toaster? I'd like to
double check we are seeing the right behaviour but it depends how you
actually ran the builds as to whether this was the right result.

Since toaster records all the log information, is it not able to compute
an individual build log from that data?

The reason I'm reluctant to just add some kind of "build log"
functionality to bitbake is that at the commandline level, I think it
would mislead people. In theory, a "build" would be the output between
BuildStarted and BuildCompleted, the question is then what happens to
the output before and after these events.
