That's not true - one can check just the build-id note even if one finds it by
the ".debug" suffix; just GDB currently does not do so.  Although I do not
think it is useful in any way - if build-id is already present it can be used
for the filename as it prevents name clashes during multiple versions
installed, moved files etc.
