make it more clear what 'Tier 2' (without host tools) means

When saying that Rust "builds official binary releases for each tier 2 target", it's not at all clear that this does not mean we build a compiler and cargo for that target.

## Tier 2 with Host Tools
Tier 2 targets can be thought of as "guaranteed to build". The Rust project
builds official binary releases for each tier 2 target, and automated builds
ensure that each tier 2 target builds after each change. Automated tests are
builds official binary releases of the standard library (or, in some cases,
only the `core` library) for each tier 2 target, and automated builds
ensure that each tier 2 target can be used as build target after each change. Automated tests are
not always run so it's not guaranteed to produce a working build, but tier 2
targets often work to quite a good degree and patches are always welcome!
