I would only add the deploy step to master branch (and release
branches?). As long as we don't run into a travis timeout, I don't care.
(And if we do, we might look into getting a ccache setup although it
will be more complicated than what we can do for the linux builds at the
moment)

If we find a way to do that for PRs, it would be a nice enhancement.
A few things need to be sorted out first like file storage and how to
easily provide a link from the PR.

If possible (timeout) I'd go for the big ones for master builds in a
first step.

I really like this plan.
