maint: make it easier to copy FORTIFY_SOURCE snippet
While libvirt intentionally avoids -Wundef (after all, C99 guarantees sane semantics of treating undefined macros as 0), the glibc insanity of #warning on _FORTIFY_SOURCE coupled with what some people feel is the black magic of autoconf means that other projects are likely to copy our snippet verbatim. We can be nicer to other projects by making it easier to integrate into projects that use -Wundef. Suggested by Christophe Fergeau. * m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Be nice to other projects using -Wundef. (cherry picked from commit 1c2edf0fbd4d20b3955cd5a3d8986413e94fba51)
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
