There is no one correct way to suppress these records; it is a case of 
whatever works works.  But if you want an opinion then I would recommend 
option 1) with an explicit start value of 0.  (Assuming that that 
works).  This is the clearest option.  It might also be useful to add a 
comment to whatever makefile or build mechanism you are using where this 
command line option is added to objcopy explaining why it is needed.
