I've also just done that on mine during the last two days.

To me, it looks as if you have installed (at least) libcxx, you can
start over again with the rest of the toolchain.

But a completely fresh install messes up.

Another thing I could do was re-compile the toolchain as universal on
the i386 and then just copy it over to the x86_64 system.
