The following binutils 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
For gcc...

* config/moxie/moxiebox.h: New file.
For libgcc...

* config.host: Add moxiebox configuration suppport.
