Works fine with
$ gcc -v
Using built-in specs.

Does it also happens with -fuse-ld=gold?

I can also reproduce this on Arch linux.
Yes it still fails if I change the Makefile to set
LINK = g++ -fuse-ld=gold
However changing
CXX = g++ -O2
makes it pass.
$ gcc -v
Using built-in specs.

Confirmed also on trunk. P1 because of a regression on the branch that wasn't
released yet.
