Subject: [PATCH] usbip: tools: fix build error for multiple definition
Git-commit: d5efc2e6b98fe661dbd8dd0d5d5bfb961728e57a
Patch-mainline: v5.9-rc1
References: git-fixes

With GCC 10, building usbip triggers error for multiple definition
of 'udev_context', in:
- libsrc/vhci_driver.c:18 and
- libsrc/usbip_host_common.c:27.

Declare as extern the definition in libsrc/usbip_host_common.c.
