Subject: [PATCH] build-sys: revert use of ln relative option.

Systemd build system now uses the `--relative` option from `ln(1)`.
This option was added to GNU coreutils 8.16, which is not widely
deployed yet by GNU/Linux distributions (not available in Debian Wheezy
for example).

This patch reverts the following commits:

- "build-sys: Fix move-to-rootlibdir"
- "build-sys: work around broken ln --relative -s -f"
- "build-sys: prefer using ln --relative -s where appropriate"
