[Patch, moxie] Add moxiebox target

[Anthony Green <green at moxielogic dot com>]

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
