Since world can not be build anymore at the moment with the use of
-stdlib=libc++, wouldn't it be well-advised to make a note in UPDATING?
I was wondering that so few CURRENT users are going to use the new
libc++ for building world.

If it is an official advise NOT to use libc++ at the moment and I simply
didn't get the message, please consider my complain without a subject
anymore.
