+Note that adding a new target that wants to support `std` would transitively
+require `cc` and `libc` support. However, these would like to know about the
+target from `rustc` as well. To break this cycle, you are strongly encouraged
+to add a _minimal_ `#![no_core]` target spec first to teach `rustc` about the
+target's existence, and add `std` support as a follow-up once you've added
+support for the target in `cc` and `libc`.
