The idea would be to add it to our src tarballs, and have it be used
in more places. (If nothing else, it would be nice to have in the tarfiles
as-is. The only reason I haven't just added it is that I don't know where
it should go) 

Whether or not it's worth doing in light of the below, I can't say. 
I don't think it's likely that I'm ever going to install ETICS on my 
laptop just to build Condor, but at the same time it's not a 
big deal for me to have to build the externals ahead of time and put them
somewhere configure can find them.
