Complete tier 3 target information

There are a number of tier 3 targets with missing support information on the Platform Support page. Let's fix that!

If you're maintain one or more of these targets can you answer the following questions:

• Does your target have std support or is it limited to no_std?
• Does it support running tools like rustc and cargo natively on the target?

You can either answer here or send a PR to update the Platform Support page.

I'll start trying to ping maintainers as I figure out who they are.

Start with the Platform Support page linked in the issue and review the unchecked tier 3 target entries. For each target, gather whether it has std or only no_std support and whether rustc and cargo run natively, using responses from the relevant target maintainers. Done means the missing support information is answered and the page is updated.
