another clang build problem, LLVM_ENABLE_LTO=thin causes make to break when specifying -j


I must be doing something wrong here or missing something.

When I add -DLLVM_ENABLE_LTO=thin to the cmake command and then try to make clang with make -j n, it jumps immediately to trying to link and fails. This is true with -j 1, so it is something about the make and not parallelism. I am running the system make on ubuntu 14.4 (don’t ask…)
