   4 Subject: usbip: tools: fix build error for multiple definition
   5
   6 With GCC 10, building usbip triggers error for multiple definition
   7 of 'udev_context', in:
   8 - libsrc/vhci_driver.c:18 and
   9 - libsrc/usbip_host_common.c:27.
  10
  11 Declare as extern the definition in libsrc/usbip_host_common.c.
