kbuild: fix interaction of CONFIG_IKCONFIG and KCONFIG_CONFIG
If you try to build a kernel with KCONFIG_CONFIG set (to a value not equal to .config) and that config sets CONFIG_IKCONFIG then the build will fail with: make[1]: *** No rule to make target `.config', needed by \ `kernel/config_data.gz'. Stop. because the kernel/Makefile contains a direct reference to .config. This issue has been present since the introduction of KCONFIG_CONFIG in 14cdd3c402bf7c66f0bcd76e290f0770a54a4b21.
