"haha", she thought, "this patch does not affect linux or darwin, so it can go straight to master!" Unfortunately, she did not realize that the relevant version of elfutils had not yet reached master.

I also had to add an additional commit that actually fixes the freebsd build. It is, unfortunately, an enormous mess.
