I sent a pull request that makes the BuildFactory definitions simpler
using a single create_build_factory() function:

https://github.com/b1-systems/buildbot/pull/1

Keep in mind that BuildFactories differ not just by repo/branch but
also:
 * in-tree or out-of-tree
 * extra ./configure arguments
 * gmake instead of make

I think this means it is not as simple as defining a single
BuildFactory.
