I usually don't interact with SRPM files directly when finding out such things. I go to the Fedora git and poke around in there. Before, I hadn't found the Debian git web interface and as such had no easy access to what build commands/options were being used. It's still less than ideal (IMO) because it's an exploded tarball and everything is split into many files under debian/, but another search binding to go straight there is possible (debian-dir-only patches on patch-tracker seems to be what I want for the most part). I'll have to work on getting some of the changes for uzbl upstream (man pages, a bashism patch, a .desktop file, and some other things).
