Comment (by alexcrichton):

 Hm so if LLVM is compiled exactly the same way that is indeed a little
 worrisome. One other thing we do is that if we're compiling an in-tree
 LLVM we specify the `LLVM_RUSTLLVM` define for C++ code (here -
 https://github.com/rust-
 lang/rust/blob/bf1e461173e3936e4014cc951dfbdd7d9ec9190b/src/bootstrap/compile.rs#L736-L740).
 That's used for a few minor features but none that should touch the
 reproducibility of the build in theory...

 I'm running out of ideas unfortunately :(
