I would prefer the latter; we could enable the option only if systemd is
installed, which can be checked with pkg-config.

By the way, those files are creating another problem on multilib
environment:
https://bugzilla.redhat.com/show_bug.cgi?id=1426678

The problem is that the unit file contains arch-dependent path for
p11-kit-proxy.so, which is installed under $libdir.  We worked around
this on Fedora by splitting the package, but perhaps it might be still a
problem on other distributions.

One solution to this would be to add a dedicated command that exports
the proxy module, without specifying the path (e.g. p11-kit
remote-proxy).  However, since this systemd stuff is added for
NetworkManager, I would like to hear opinions from them.

Any thoughts?
