"$DIR" might not be a full path and it might not have `pwd` as ".." directory. So use `cd -` to undo the first `cd` command. Also, use `basename` to make a symbolic link with a relative path. This doesn't matter yet but it will when for example the commands to clone OVMF is been run from tools/ rather than tools/firmware/.
