    powerpc: split She math emulation into two parts · e05c0e81

    For some SoC (such as the FSL BookE) even though there does have
    a hardware FPU, but not all floating point instructions are
    implemented. Unfortunately some versions of gcc do use these
    unimplemented instructions. Then we have to enable the math emulation
    to workaround this issue. It seems a little redundant to have the
    support to emulate all the floating point instructions in this case.
    So split the math emulation into two parts. One is for the SoC which
    doesn't have FPU at all and the other for the SoC which does have the
    hardware FPU and only need some special floating point instructions to
    be emulated.
