DATA_GOT, SDATA_GOT

[Sandra Loosemore]

I'm trying to understand the purpose of DATA_GOT and SDATA_GOT in 
ld/scripttempl/elf.sc.  It looks to me like if an emulation defines 
DATA_GOT and doesn't define NO_SMALL_DATA, it'll end up with the 
.got-related bits being emitted in both places.  Is this 
intentional/correct/useful/whatever?

I looked back in the mailing list archives to the time when these 
variables were added to elf.sc and didn't see any discussion about this 
(it was part of a much larger group of changes for powerpc).  And, they 
aren't documented at all at the top of the file where the other 
customization hooks are listed.  Can anyone clarify their purpose and usage?
