rpm-list is better place for this.

I assume you want the payload to be rsyncable.  There are a few rpm
delta implementations:

http://toast.debian.net/~may/rpmdelta/
http://primates.ximian.com/~pzb/rpmdelta-0.0.3.tar.gz

To produce a delta off the original rpm.

This is not what you need (but yes you can turn off brp-compress with a
%define).

brp-compress compresses man pages/info - it will not affect rsyncs
ability to handle the rpm payload which is compressed cpio.
