Comment (by gk):

 Okay, while still bisecting my way done to the Rust commit causing this I
 looked a bit closer at where the differences are showing up. It turns out
 that the `libstyle` rlib is already the problem and extracting that
 archive shows me that

 a) rust.metadata.bin matches and
 b) the bc.z files differ
 c) the .o files differ

 Alex, Manish: Does that give a hint in which direction we need to look?
 Like, is b) an indication that this is a clang issue? Or do the results
 give some other clues? For instance would it be helpful analyzing the bc.z
 files, if so how?
