> This adds enough infrastructure for binutils to support gotdata
> relocations on Sparc.  It doesn't yet, however, add code to perform
> the code optimizations possible using these relocations.  I will add
> those later as a follow-on patch.
 ...
> Regression tested on sparc{,64}-unknown-linux-gnu
