That works fine, also with -j$BIG .

Ah.  I configure with O=, but then cd to that dir and build without O= .
Also not in a subdir of the kernel source tree.

make ARCH=$ARCH CROSS_COMPILE=$TARGET- -C $KERNEL_SRC O=$PWD $DEFCONFIG
make ARCH=$ARCH CROSS_COMPILE=$TARGET- $MAKEOPTS

(everything run in the build dir).
