Comment (by kencu):
This commit <https://reviews.llvm.org/D25932> would appear to explain why
LTO is now automatically invoked on newer llvm versions, I think. It would
appear to have become the default to invoke LTO when this commit was
included in an llvm version release -- presumably after 3.9.0 and before
3.9.1 as yours invokes it automatically whereas mine does not.
So I guess the remaining question is why ld64 finds the LTO library
without apparent troubles on my machine, but not on your machine...
