[Xen-devel] [PATCH v2 2/2] tools/configure: Check if pixman is present on the system when building QEMU

[Julien Grall <julien.grall@xxxxxxxxxx>]

QEMU upstream requires the use of pixman. When pixman is not present the
system, the configure of QEMU will fail with:

ERROR: pixman not present. Your options:
         (1) Preferred: Install the pixman devel package (any recent
             distro should have packages as Xorg needs pixman too).
         (2) Fetch the pixman submodule, using:
             git submodule update --init pixman

I think we can use by default the version on the system. So check it
a Xen configuration time to avoid a build issue later.
