linux: Import minimal defconfigs as defconfigs
Now that minimal kernel defconfigs are used in Buildroot, the problem is that copying those minimal configuration files to .config in the kernel source tree does not work, as kconfig will ask interactively what should be the value for all unspecified options. On suggestion on Sam Ravnborg, the easiest way to solve this is to import the minimal defconfig file as a defconfig inside the kernel tree (in arch/$(ARCH)/configs) and configure the kernel with it.
