Patches should have a description and a Signed-off-by line.

Also, could you submit this patch upstream? I'd like to see if upstream
is willing to accept such a patch, since it is more or less a "feature"
patch, and we prefer to not have to carry such patches forever.

This explanation seems weird: why would you link against libelf and not
use it?
