Since forever, we run 'menuconfig' automatically on an unconfigured tree. However, this does not help users that much: - If they read the documentation, they should already know to run make menuconfig first. - If they haven't read the documentation, dropping them in menuconfig isn't very helpful. - It's a likely that the user didn't intend to be in an unconfigured tree (e.g. wrong O= specified), so starting menuconfig (and polluting this wrong O= directory) is not very helpful. - It's possible that the user really doesn't want menuconfig, but instead needs xconfig, or some defconfig, or ... So, instead of trying to guess what the user needs, print an error and let the user decide what to do next.
