Raise an error if the host is using an older kernel than the target. Since qemu-user passes emulated system calls to the host kernel, this prevents usage of qemu-user in situations where those system calls will fail. This is based on an original patch from Frank Hunleth <fhunleth@troodon-software.com>, but completely rewritten in a different way: * Instead of using shell based testing, we use pure make tests, which allows to detect the problem not when host-qemu starts to build, but at the very beginning of the entire Buildroot build. * Instead of looking at $(STAGING_DIR)/usr/include/linux/version.h (which requires having a dependency on the 'toolchain' package, which is a bit unusual for a host package), we use the BR2_TOOLCHAIN_HEADERS_AT_LEAST Config.in option which tells us the version of the kernel headers used in the toolchain.
