ARM: packed-struct-vec

packed-struct-vec rpass test fails with "Bus error". Could be an LLVM problem, also could be a Rust problem.

Given that android is tested nowadays, it looks to me like this just got lost in the shuffle. Let me know if closing this is wrong for some reason.

@steveklabnik This looks like it needs to be open, it's ignored on android: https://github.com/rust-lang/rust/blob/master/src/test/run-pass/packed-struct-vec.rs#L11
