[Qemu-devel] [PATCH 2/2] configure: Fix set-but-not-used warning in Xen 4.1 probe

[Peter Maydell <peter.maydell@linaro.org>]

The Xen 4.1 probe never uses the return value from xc_interface_open(),
so was provoking a compiler warning on newer gcc. Fix by not bothering
to put the return value anywhere.
