    don't build --with-async-mode w/ libusb-compat-0.1
    
    Hello,
    
    attached is a little patch that prohibits libftdi from compiling against
    libusb-compat-0.1 (the wrapper that provides a libusb-0.1 compatible api
    for systems with libusb-1.0) when libftdi is configured with async mode.
    
    unfortunately fixing async mode for libusb-1.0+libusb-compat-0.1 is not
    trivial because libusb-1.0 comes with an os abstraction layer that hides
    the unix filedescriptor much deeper in internal structures. but failing to
    build is imo much better than segfaulting at runtime.
    
    yours,
     - clifford
    
    PS: The USB_CLASS_PTP define is not present in any libusb-0.1 release
    and has been added to libusb-compat-0.1 only afaics.
