Yeah, thinking about this I agree with Kay and Harald.

If it is desirable to cross-build systemd on such an old distribution
I'd recommend sticking an alternative "ln" implementation into $PATH and
making sure it is preferred when building systemd. This could just be
the shell script that was posted and it could handle --relative
invocations, and for everything else defer immediately to the real ln...

I have now added a configure check that makes sure that ln supports
--relative, so that this is detected early on.

Hope that makes sense...
