Nah, I think that's probably fine without an explicit `-ggdb` test - though with the test as-is, wouldn't it fail on macos machines, where they'll implicitly default to `-glldb` and so `-ggnu-pubnames` won't get passed, so the check on line 14 of split-debug.c will fail? So maybe that has to be removed from there and only checked via explicit tuning flags, in which case adding a `-ggdb` test would be necessary (though it could share the CHECK lines from the `-glldb -ggnu-pubnames` test)
