You are missing one important bit of information. Latest gcc in unstable
is gcc-3.3, which supports 64bit compiled, but it cannot compile working
kernels.
Problem is that even if you have egcs64 installed, the kernel make
system will detect gcc as suitable and not bother with
sparc64-linux-gcc. That's why I said, and I'll repeat, you need to add
CC=sparc64-linux-gcc to your environment, or edit arch/sparc64/Makefile
and delete the CC= line and add CC=sparc64-linux-gcc
