safe_arch crate doesn't build in vendored mode (fails to copy all required sources) when precise_srcs=true.

[Chip Collier]

Hello!

The safe_arch crate only includes modules in the source tree when using precise_srcs = true, apparently because it uses a macro to actually import the module.

I'm not entirely certain what the action item for this would be, but I don't think this an unusual thing for crates to do.

Thanks!

Ok, I've now found the docs folder!
