To expand on DanielJ's comment.  When fixing a GDB / BINUTILS autoconf 
botch, the final patch _always_ results in the addition of the sitefile 
stuff.  To me, having that in the diff _is_ normal.

Should it instead be re-generated with pure 2.13?  Better first question 
though is what did GeoffK use?  (I'm guessing that it was Geoff's regen 
that broke it).
