 At the moment I am trying to find out why and where it gets set that the
 function is available. It seems that the configure script in libbacktrace
 is introducing the error:

 {{{

 Although I have enough time to patch that script manually to make it
 partially more verbose for debugging, I seem to fail doing so and I think
 I'll create a patch file for this purpose… After sleep.
