The benefit is that in general people who want to build QEMU
from source can do so. I don't want us to be the kind of
project that needs latest-and-greatest-foo for everything
to build, because that sort of project is pretty infuriating
to try to work with if you're an occasional contributor.
"Builds on LTS distros" is an easy-to-express way to keep
things from getting out of hand.

Plus a bunch of the build machines we do testing on are
not running bleeding edge distros, and as Connie says plenty
of developers do QEMU development on non-bleeding-edge versions
(my primary dev box run an LTS Ubuntu).
