As far as it is necessary to go for a linker and a dynamic loader to be 
written, from the EABI specs, by independent people and for the results to 
work together.  These are independent tools that share an interface.

Nick, I think I'd prefer that the patch were removed until we have an EABI 
spec for this area.
