it seems make oldconfig change setting between different setting...
diff .config config.full.good 4c4 < # Thu Jul 10 00:52:52 2008 --- > # Thu Jul 10 00:40:03 2008 295,296c295 < CONFIG_CC_STACKPROTECTOR_ALL=y < CONFIG_CC_STACKPROTECTOR=y --- > # CONFIG_CC_STACKPROTECTOR is not set
it seems some recent change doesn't like stackprotector.
