I not sure to understand the meaning of these lines in spec file:

%{?dist: %{expand: %%define %dist 1}}

I understand "if %{dist} exists, we define a var and its name will be
the string that %{dist} contains (expand), and this new var will
contains "1". Is that right ?

And so we use it, if defined :
%{?rh8:%define _without_elfutils 1}

now if i call --define "dist rh8" ; and I disable the first line I
mentionned in the spec file (the one with dist expansion), then i notice
that %{rh8} still exists and contains "1" : is it normal ?
