## Testing of std on Tier 2 platforms

Maybe we could use something like toolstate tracking.

Breaking these platforms should be okay, since they're tier 2.

Scripts/tooling to spin up a VM, even just locally, would be very useful.

Many tier 2 platforms don't actually comply with the tier 2 policy. We could start pushing towards that. Maybe we should ask for instructions for a VM.

Running just the std tests (not the rustc tests) in qemu with software emulation should be possible.

## Maintenance of the cc and cmake crates

cc: https://github.com/alexcrichton/cc-rs/issues/663

cmake: https://github.com/alexcrichton/cmake-rs/issues/127

We should transfer them to rust-lang.

Josh Triplett notes: A lot of information that's part of `cc` should also be part of cargo or rustc: which linker to use, etc.

We should ask for help with infrastructure to automatically publish new versions after testing.
