[Qemu-devel] [PATCH 03/11] configure: Fix build with capabilities

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

From: Stefan Weil <sw@weilnetz.de>

Since commit 417c9d72d48275d19c60861896efd4962d21aca2 all configure tests
normally run with -Werror. Some of these tests now fail because they
raised a compiler warning.

This patch fixes support for capabilities.
