Makefile: Just error out if no .config exists

Currently coreboot runs the 'config' command if no .config file exists.
    This isn't what anyone wants, and is particularly frustrating for tools
    that automate the build, where the build just hangs waiting for input.

Instead, just show an error message and then exit the build.
