If not, it would be great if we could at least teach lldb to do this so that we can start thinking about splitting debug info into separate packages for ports (and providing it as an optional install for everything). Not yet, but it's trivial to add for at least LLDB. My end goal is what you describe - kernel, base system userland, and packages/ports can all provide standalone debug packages which will install to a consistent and well-known location, and be picked up automatically by the debugger. Part of this project depends on moving past our old binutils though, so we can start using the build-id ELF note to link the executable or library with its associated debug data.help
