This patch below will likely fix the build failure.
But note that gcc-4.2.x is very widely known to miscompile
the sparc64 kernel, particularly on SMP, so even if you get
a build the kernel you end up will be mostly unusable.
I would really recommend you stay with gcc-4.1.x unless you are going
to work on fixing those gcc-4.2.x miscompilations, and I'm already on
the hook for that :-)
