This is a property of the target, just like whether or not `#' is the
assembly comment character.  So, we'd just put it in the target 
configuration file.

The conservative (in terms of minimizing changes to existing configuratin 
files) approach would be to turn it on by default, but allow targets to 
turn off any builtins they don't support.
