Eric Blake f6e7865d27 build: allow building with newer glibc-headers and -O0 
glibc 2.15 (on Fedora 17) coupled with explicit disabling of
optimization during development dies a painful death:

In file included from /usr/include/limits.h:27:0,
                 from /usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/limits.h:169,
                 from /usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/syslimits.h:7,
                 from /usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/limits.h:34,
                 from util/bitmap.c:26:
/usr/include/features.h:314:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]
cc1: all warnings being treated as errors

Work around this by only conditionally defining _FORTIFY_SOURCE,
in the case where glibc can actually use it.  The trick is using
AH_VERBATIM instead of AC_DEFINE.

* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Squelch
_FORTIFY_SOURCE when needed to avoid glibc #warnings.

         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.
