That's the correct defaults, according to the GNU Coding Standards which
autoconf uses in generating the configure script.  The fact that
configure is defaulting --libdir to ${prefix}/lib rather than your
desired ${prefix}/lib64 means only that RHEL is buggy for not installing
a config.site override that alters the defaults for it's particular
choice of preferred libdir; but that's a distro bug [1] that affects
much more than libvirt, and something that libvirt should not have to
work around.  It does NOT affect rpms built for the the distro, since
rpms are correctly built with --libdir specified in the right location.
 Meanwhile, the correct way to fix things is by doing:

./autogen.sh --prefix=/usr --libdir=/usr/lib64
--enable-compile-warnings=error

In fact, you can even use:

./autogen.sh --system --enable-compile-warnings=error

as short-hand for setting up _all_ the default paths (including other
settings, like --sysconfdir=/etc) needed for installing a self-built
libvirt into the default distro locations on Fedora-based distros,
including RHEL.
