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.
