I was looking at wiring up `.gdb_index` (or `.debug_names`) support in our packaging today and found debugedit's `find-debuginfo` supports `-i` to create `.gdb_index `by calling `gdb-add-index`, but it does this without `-dwarf-5`, so it's creating the deprecated/obsolete `.gdb_index` instead of `.debug_names`. `find-debuginfo` should pass -dwarf-5 to `gdb-add-index` to create `.debug_names` instead. See PR31363 as well.
