Differentiate a src.rpm build from a binary rpm build

[Mihai Maties <mihai xcyb org>]

Hello,

I have a small shell script that figures out the linux distribution the rpm 
was built on to include a small part into the "release" field so the final 
package will be named something like: name-version-4.rh9.i386.rpm. The 
problem is that the script is executed also when I build the src.rpm file 
thus the name "mdk92.src.rpm" it's pretty annoying...

How can I differentiate inside the spec the invocation of a src.rpm build from 
the binary build ?
