Previously, Soft_emulate_8xx was called with no implementation, resulting in
build failures whenever building 8xx without math emulation. The
implementation is copied from arch/ppc to resolve this issue.
However, this sort of minimal emulation is not a very good idea other than
for compatibility with existing userspaces, as it's less efficient than
soft-float and can mislead users into believing they have soft-float. Thus,
it is made a configurable option, off by default.
