I'm not sure if it's because upstream's autoconf code is not fine enough. Either way it works for Arch Linux (x86_64), but not the builds here.
systemd will keep on considering squid to be "activating" and eventually terminate squid when the service reaches the activation timeout, since it is not getting a notification from squid.
