I believe at one point, each binary .rpm encoded the values of all  
the macros as they were set at build time. Not sure if that's still  
the case, and I forget exactly how it was implemented (maybe as a  
RPMTAG stored in the .rpm?)

Each binary .rpm also stores the md5 or sha1 of the .src.rpm that it  
was built from, which means you can tell whether a binary package was  
built from unmodified .src.rpm's.

Best,
