kconfig: use /boot/config-* etc. as DEFCONFIG_LIST only for native build
When the .config file is missing, 'make config', 'make menuconfig', etc. uses a file listed in DEFCONFIG_LIST, if found, as base configuration. Ususally, /boot/config-$(uname -r) exists, and is used as default. However, when you are cross-compiling the kernel, it does not make sense to use /boot/config-* on the build host. It should default to arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG). UML previously did not use DEFCONFIG_LIST at all, but it should be able to use arch/um/configs/$(KBUILD_DEFCONFIG) as a base config file. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
