Minimal math emulation for 8xx

└─> Minimal math emulation for 8xx

Older arch/ppc kernels still emulated a few floating point
instructions such as load and store, even when full math
emulation is disabled. Say "Y" here if you want to preserve
this behavior.

It is recommended that you build a soft-float userspace instead.
