HI16 / LO16 relocations.

[Ralf Baechle <ralf@uni-koblenz.de>]

Mark, for now I'm just posting this in the hope it may ring a bell.
It seems like HI16 / LO16 relocation pairs are not handled correctly
This may result in ``la $reg, symbol'' ending up after the final link
as ``la $reg, symbol + 0x10000''.

I'll try to come up with a resonably small example tomorrow; right now
I've just discovered this problem and can only show the problem in
the diffs of disassembler listings between the two builds of a Linux
kernel with binutils 2.8.1 and cvs-binutils.
