Are those floating point stores? Is that really needed?

For reference, the PowerPC port builds with -msoft-float, for a couple
reasons:
- there are some PPC without FPUs (though admittedly none that run GRUB
right now)
- on PPC with FPUs, with some firmwares you need to go out of your way
to enable it via assembly in _start

In general it doesn't seem like there's any need for FPU in GRUB, so we
just don't use it.
