Sorry, in my previous message I was confused about the subject - for
some reason I thought you were asking about the wanna-build patches,
not the sbuild patches. My mistake.

The sbuild patches are all in the 0.65 in jessie. So if we just move
to using this on the buildds, then that should work fine.

Re that move, do we still need to produce a special buildd version?
There is still a diff between the mainline version and the buildd team
version, but these days it seems to just be the buildd config file
which probably just ought to go in the package?
