Use linkat() instead of link() for portability sake
POSIX does not says wether link(2) on symlink should link on symlink itself or on target. Linux use symlink, most other systems use target. Using linkat(2) allows the behavior to be specified, so that the behavior is portable. Also fix configure test for NetBSD linkata(2), which ceased to work.
