This same error occurred when I tried to emerge qtcore-4.8.5, so it's probably something on my system, but I don't think I've set the USE flag x64-freebsd anywhere. This is an x86-only system.
Could you try to sync your portage tree to see if that fixes the issue?
Particularly the file profiles/arch.list should be up to date.
