After digging on this, here is the right way:
 echo 'int main () { return 0; }' > foo.cc
 clang++ -c -flto -O2 foo.cc -o foo.o
 clang++ -flto -use-gold-plugin -O2 foo.o -o foo

I added the -use-gold-plugin arg. You will need llvm-dev version 3.0-9
and binutils-gold.

I will ping upstream to ask if they recommend a strong dependency on ld
gold and a default usage of -use-gold-plugin.

Thanks for spotting that and the easy test case (I love easy and lazy
test case).
