My take on this is that sysconfdir and localstatedir should always default
to /etc and /var, respectively, and never to something based on the prefix.
Neither the location of system-wide configuration files nor the location of
"local" (not part of a shared filesystem) writable storage is a function of
where you happened to decide to install the software.
