Right. We inject -g into the default build flags. We extract the
resultant debug info into a .debuginfo RPM.
The original motivation behind annobin was to verify how well the
injection mechanism worked. We originally wanted to do something like
what Egeyar has done, but it's been proposed in the past and was highly
controversial. Rather than fight that problem or have a Red Hat
specific patch, we built annobin/annocheck which (IMHO) handles this
kind of need quite well.
