    MIPS: kernel: elf: Improve the overall ABI and FPU mode checks · 46490b57

    The previous implementation did not cover all possible FPU combinations
    and it silently allowed ABI incompatible objects to be loaded with the
    wrong ABI. For example, the previous logic would set the FP_64 ABI as
    the matching ABI for an FP_XX object combined with an FP_64A object.
    This was wrong, and the matching ABI should have been FP_64A.
    The previous logic is now replaced with a new one which determines
    the appropriate FPU mode to be used rather than the FP ABI. This has
    the advantage that the entire logic is much simpler since it is the FPU
    mode we are interested in rather than the FP ABI resulting to code
    simplifications. This also removes the now obsolete FP32XX_HYBRID_FPRS
    option.
