[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=124edd4d5f4cddbd40a1113dccc255c5956bd9ae
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Install a 'vi' symlink to win over busybox vi (more features) and in
case busybox isn't around, for people expecting plain simple 'vi' to
call the editor.
