I have gotten c30- and tic30- to work now.  But the bigger issue
is settling on a real name.  gcc uses c4x-.  The older patches
from the gcc-c40 group (Michael Hayes, et. al.) use c4x-.

I can provide a patch if we can settle on a direction.  I hate to 
add support for 3 name variations of a new target unless there is
good reason. :)
