MIPS64 XLR support patch?

[Matt Thomas]

Given that the changes in 

http://sourceware.org/ml/binutils/2009-01/msg00383.html

don't seem to be in binutils, was there any reason why it wasn't
picked up?  Any reason why they can't be merged now?

I'd rather not have these changes be a local modification to 
the NetBSD's repository copy of binutils but will do so if needed.

BTW, the patch applies cleanly (no rejects) to 2.19.1 ...
