 As noted in the other e-mail I suggest using it everywhere, for 
uniformity, and I think using the old name for the new assignment should 
provide maximum compatibility.  We could rename the old assignment to 
DT_MIPS_RLD_MAP_LEGACY then.

 Can you think of a scenario where it would not work?

 Alternatively, we could cook up a generic DT_GNU_RLD_MAP tag for 
platforms that want to opt in to a read-only dynamic section/segment and 
start using it with the MIPS target first.  I think I like the latter a 
bit better, any thoughts, anyone?
