failure at link time 3.9.1

As a note, I experimentally attempted to build 391 branch "just llvm +
clang" on ubuntu the other day, and got this:

Actually I retried it with 3.9.1 final today and it seemed to work
fine (this was an RC) so I assume it was fixed, thank you, sorry for
the noise.
Merry Christmas!
