It turns out that the symlink may exists already by the time the toolchain Makefile gets an opportunity to run. While we asked to replace the target, ln doesn't do so until after dereferencing the existing symlink. This results in an unintended symlink that refers to itself. Instead, create the link without dereferencing any symlinks by using the -n option. Signed-off-by: John Szakmeister <john@szakmeister.net> SVN-Revision: 36140
