I'm asking about style.

In expanding target architecture entries I'm constantly adding
references to other vector members.  How should I be adding the cross
reference links?

For instance:

	REMOTE_BREAKPOINT 
	LITTLE_REMOTE_BREAKPOINT 
	BIG_REMOTE_BREAKPOINT 
	       Similar to BREAKPOINT, but used for remote targets. 

	       BIG_REMOTE_BREAKPOINT and LITTLE_REMOTE_BREAKPOINT have been
deprecated in favour of BREAKPOINT_FROM_PC. 

What magic should be added to xref to BREAKPOINT_FROM_PC.
