You mean, let gcc generate n64 code, stuff it in n32 objects, and
objcopy it back to n64? Well, it may work, but it looks more like
a test of binutils sign-extension handling than a straightforward
way of creating kernels to me.
Besides, as soon as gcc handles 64bit expansions itself we need
such an option anyway.
