    * config/arm/arm.c (arm_libcall_uses_aapcs_base): Use correct ABI
    for __aeabi_d2iz/__aeabi_d2uiz with hard-float.

    * config/arm/arm.c (arm_libcall_uses_aapcs_base): Use correct ABI
    for double-precision helper functions in hard-float mode if only
    single-precision arithmetic is supported in hardware.
