For just creating an src.rpm, I suppose you can use a simple spec 
conditional, eg

# permit src.rpm creation on older versions
%if %{fedora} >= 21
%{load:...}
%endif

Anyway, like mentioned earlier, %{load:%{SOURCE4}} would not have worked 
yesterday as %{load:} didn't macro-expand its argument, that has been 
fixed in rpm-4.11.90-0.git12844.3.fc21 (just building now). So thanks 
for trying to use that feature :)
