        PR libffi/31937
        * src/powerpc/ffitarget.h: Introduce new ABI FFI_LINUX_SOFT_FLOAT.
        Add local FFI_TYPE_UINT128 to handle soft-float long-double-128.
        * src/powerpc/ffi.c: Distinguish between __NO_FPRS__ and not and
        set the NUM_FPR_ARG_REGISTERS according to.
        Add support for potential soft-float support under hard-float
        architecture.
        (ffi_prep_args_SYSV): Set NUM_FPR_ARG_REGISTERS to 0 in case of
        FFI_LINUX_SOFT_FLOAT, handle float, doubles and long-doubles according
        to the FFI_LINUX_SOFT_FLOAT ABI.
        (ffi_prep_cif_machdep): Likewise.
        (ffi_closure_helper_SYSV): Likewise.
        * src/powerpc/ppc_closure.S: Make sure not to store float/double
        on archs where __NO_FPRS__ is true.
        Add FFI_TYPE_UINT128 support.
        * src/powerpc/sysv.S: Add support for soft-float long-double-128.
        Adjust copyright notice.
