For many years, rawhide kernels have forced users to run debug builds on git snapshots by not building a non debug kernel as an option. While this has served us well, in finding occasional bugs that are less likely to surface otherwise, the performance of debug kernels has gotten considerably worse over time. After evaluating the debug configs to see if performance could be improved, it has become clear that we would have to trade off too much to regain performance. We would be better served by leaving more debug options enabled and offering a non debug kernel for all users on all builds.

Turn on debug builds for aarch64 Fedora
Fedora only did debug builds for x86 in the past. This was largely due to slow build times on other arches in koji, coupled with much smaller userbases. Let's turn on aarch64 now as those builders are much faster and the userbase is considerably larger these days. Replacing i686 here makes sense as we no longer build for that arch.
