-std=gnu++11 is more used (and much better tested) than -std=c++11.  Any chance
that fixes it for you?
FYI

The same problem on gcc 4.7/4.8/4.9 with -std=c++11 and -std=gnu++11.
It looks like a bug in the gcc but that fact does not help to build
lld.

Yup, I can confirm that.  Then the question is if LLD shouldn't compile
with GNU, even if GNU is buggy.  Personally, I think it is worth a lot to
be able to build with GCC, but I don't know how the LLD developers feel
about that.

We should make LLD to be able to build with GCC even if GCC is a bit buggy.
So you wrote that it's no longer build because of the recent change of
makeArrayRef removal? I think it's my change (r196475).

Can you confirm that you can build if you revert that change? If it has
caused the build with GCC to break, we should roll it back.
