llvm dev - Dec 2013 - [LLVMdev] GNU LLD build error? Seems that Clang likes LLD just fine.

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.

I tried this command to undo the change (which should revert to the change
just before the one you mentioned):

   svn update -rr196474

Then I built from scratch. This time it built, so I suppose it is revision
196475 that is the problem.
