This allows us to specify a user defconfig which is added on top of the default defconfig, which makes it easier for users to keep a simpler defconfig, without duplicating all the options already present in the arch defconfig. Here a very simple defconfig I've been using for several years on top of x86_64_defconfig. It works because I can rely on the fact that x86_64_defconfig is properly maintained.
