 Crap, yes, I had done a quick grep, found some hits, and didn't notice it were
patches *removing* the --relative.

 I would still very much prefer to create a relative symlink automagically. Some
ideas:

1. Install a proper host-coreutils if the system-provided one is too old
(similar to cmake). Meh.
2. Always make absolute symlinks (pointing to target dir) and at some point call
https://github.com/brandt/symlinks to convert absolute to relative.
3. Make an 'ln' wrapper that converts absolute to relative, using e.g. the shell
scriptlet from [1].

 Regards,
 Arnout
