- The unmodified upstream iproute2 package installs the ip utility in
/sbin. That is also where it thus ends up with for example Yocto
builds.
- Debian/Ubuntu installs it in /bin (and I assume that's how this came
to be), but their packaging logic provides a symlink /sbin/ip ->
/bin/ip .
- ArchLinux seems to install it in both places (as hardlinks).
- CentOS only has /sbin/ip.
- Fedora only has /sbin/ip.
So /sbin/ip should work everywhere, whereas /bin/ip does not.
In the /etc/ethercat.conf file, the MASTERX_DEVICE string is given as a
mac address or a wildcard. When we want to deploy the (same) software (image)
to a bunch of different hardware, and these computers do have more than one
interface that matches the driver, we need a way to define the device by
network interface name. This allows to also define the network device by name
(e.g. eth0, eno1, ...)

Try to reuse the configured paths as much as possible. Unfortunately, to
be able to fully expand some variable (e.g. `bindir`), these files must
be expanded by make, not by configure. This adds some complexity:

Mostly fixed omitted double quotes, some conversion of $(eval ..) to $(()).
Left the echo -n untouched, shellcheck complains about not being standard in
/bin/sh. Also, seems like some code is dublicated in ethercatctl.in and
init.d/ethercat.in.
