This change [1] appears to break building on older distributions for me,
which I use in containers for access to older versions of GCC. I see the
error with Debian Stretch and Ubuntu Xenial, which have an older
libelf-dev. Is this expected? I don't mind sticking with 1.22 for
those, I just want to be sure!
