scripts/kconfig/Makefile: Allow KBUILD_DEFCONFIG to be a target
Arch Makefiles can set KBUILD_DEFCONFIG to tell kbuild the name of the defconfig that should be built by default. However currently there is an assumption that KBUILD_DEFCONFIG points to a file at arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG). We would like to use a target, using merge_config, as our defconfig, so adapt the logic in scripts/kconfig/Makefile to allow that. To minimise the chance of breaking anything, we first check if KBUILD_DEFCONFIG is a file, and if so we do the old logic. If it's not a file, then we call the top-level Makefile with KBUILD_DEFCONFIG as the target. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Michal Marek <mmarek@suse.com>
