[Patch, moxie] Add moxiebox support

- Subject: [Patch, moxie] Add moxiebox support
- Authentication-results: sourceware.org; auth=none
The following newlib/libgloss patches introduce a new moxie-based
target called moxiebox. Moxiebox is a VM developed by the bitcoin
community to act as a secure, sandboxed execution environment for
bitcoin automation.
See http://github.com/jgarzik/moxiebox for more information.
I'm checking these changes in. There's a config.sub change as well
that I'll submit through the regular process.
Thanks,
AG
In libgloss..
