Work-around libffi's FP ABI detection. On iOS, we must use the AAPCS floating point return value calling conventions. libffi's ARM implementation will only use these conventions if __SOFTFP__ is defined, which is not the case when GCC's -mfloat-abi defaults to 'softfp' instead of 'soft'. To work around this we manually define __SOFTFP__ for Apple platforms in the ARM-specific sysv.S.
