[tex-live] small bug re installing x86_64-darwinvs.universal-darwin

[Karl Berry]

    Norbert should decide 

It's not Norbert's decision.  The universal installation of
universal-darwin was an explicit choice by Dick Koch and other MacTeX
contributors, in conjunction with me, for reasons already given on the
list.

Dick already replied that he will re-study the issue when he has the
chance, so let's please drop it for now.
