Excellent!  I am a little bit hesitant to apply your patch as it is 
however since it adds target specific code to a file that is meant to be 
generic.  Could you investigate changing your patch so that it adds a 
new elf backend function which can be called when an undefined symbol is 
encountered and which allows individual backends to decide if the symbol 
can be ignored ?
