Create an SRPM for each chroot environment instead of a single SRPM for all of them.

At the moment, I can’t see a way to build a package where the sources are in a Git repository that has a separate branch for each chroot.
The custom script approach fails because only a single SRPM can be built, which is then sent to all the chroots. And with the SCM method, no branch is passed on either. It looks to me as though the same thing is happening here. An SRPM that is then sent to the individual chroots.

In this specific case, however, a new SRPM would need to be built for each branch and then passed to the appropriate chroot.
