Heh, adding FPU support to sh4 kernels is not that much work, but i
never had energy to sit down and figure out how to handle hard vs
softfloat userlands :)

As an aside, I've just learned recently that regardless of fp support
sh3 and sh4 are not abi compatible: 64-bit args are "aligned" to
register pairs on sh4, but not on sh3.  E.g. you cannot call
snprintb(3) across abis, "uint64_t val" argument is passed
differently.
