I've been having some trouble with upgrading elfutils on an old box, as repeated installations have repeatedly died as follows:

A quick google indicitated that symbol comes from linux-headers, and it turns out I still had linux-headers 3.9 installed ( and nothing I've done in the last year or so prompted it to upgrade )

After upgrading linux-headers to 4.8 ( and no other changes ), installation
completed.

linux-headers-4.3 also prove to be good, but linux-headers-3.18 ( still one of the stable options for amd64 )
replicates this error.

Though <=elfutils-0.166 is unaffected by this problem on linux-headers-3.18

elfutils-0.168 fixes this by adding a fallback define
