Subject: Major overhaul and cleanup.  Support for .ubi image file
 installations.

Only compile&install a minimum host Gforth for bootstrapping the target
Gforth, removing strange emacs-dependencies that cropped up earlier.

Image file can now be built on the nanonote using 'gforth-update-image'
command.  Also, Gforth is now run through a wrapper that calls
'gforth-update-image' automatically, if necessary.

Also first attempts at supporting libcc C-interface libraries pre-compiled on
the host.

Tested to compile on amd64 and i386.
