Well, it seems pretty obvious that actually expanding the %debug_package
macro (which includes the extra %package, %description and %files
sections) _somewhere_ in the spec is indeed necessary to generate
debuginfo.  But that commit doesn't say anything about why the
conditional on %buildsubdir needs to be there.

I guess it would be fun to see what breaks (and how it breaks) when you
use just:

%install %{?_enable_debug_packages:%{debug_package}} \
%%install \
%{nil}

instead.  But I'm not going to have time to do much of that today.
