If we add it to the documentation the question is if we should also 
document environment variables for builds with make. But maybe that is 
for a separate patch.

As for documenting it in testwrap: that does not feel very useful to me 
since people who know that this is where they should look likely already 
knows about these. It is a pretty hidden place. Hmm, not sure where such 
information belongs.
