The powerpc architecture, only, emulates the termios ioctls using the glibc termios structure. Export the real kernel ones as the termios2 interface; although the kernel doesn't call it termios2, it is exactly the termios2 interface, and it avoids the namespace clash between the emulated ioctls and the real kernel ioctls.
