In my test infrastructure, /lib/modules/$Kver/build/.config doesn't
exist. That's because I build the kernel without any modules, and
then launch kvm using its --kernel command-line option. This really
helps with development velocity, since the developer doesn't need to
waste time installing the kernel, and/or building a kernel rpm or
dpkg. Instead, kvm can just launch the kernel directly out of the
build tree:
/usr/bin/kvm ... --kernel /build/ext4/arch/x86/boot/bzImage ..
So it would be nice if _has_kernel_config also checks to see if
/proc/config.gz exists, and if so, tries to use it.
