It is build-time only, unfortunately.  There was a discussion about
that last month, where I was initially confused about the problem:

The problem is that I do not know whether we can make it work or not.
It's on my agenda of things to do, but right now, and for the next
few weeks, that's as much time as I have to help on that topic.
Perhaps someone else might want to jump in and help?

Kai is the author on the bfd end of things, so perhaps he could change
that part so as to make it dynamic, as opposed to static?

Just so you know, I understand what you are asking and why, but
unfortunately, just as above, I do not think I will have the resources
to address all that before we get 7.2 out. Someone else will have
to step in for the group.
