Adding missing symlink to dynamic loader.

As the release script does not copy over files from the currently
running system anymore, it has appeared that some binaries are
looking for the dynamic loader in /lib instead of /usr/lib.

It has been replaced by a symlink to ensure compatibility with
binaries, until the path is updated in all the toolchains to be
the same.
