As far as I know the bash-completion directory is not distro dependent,
but it moved at some point (2011) from /etc/bash_completion.d/ to
/usr/share/bash-completion/completions/. While backward compatibility is
provided with the former location, it is now recommended to use the latter.

So one idea could be to check (in iproute2 Makefile) for existence of
/usr/share/bash-completion/completions/ directory, and if not found to
fall back to /etc/bash_completion.d/. If none is found, use
/usr/share/bash-completion/completions/. Does this seem correct?
