Hi,

Running:

make buildworld TARGET=arm TARGET_ARCH=armv6 MAKE_JUST_WORLDS=yes 
SUBDIR_OVERRIDE=sys/modules MODULES_OVERRIDE=linuxkpi -DNO_CLEAN

I get:

And when running:

make -DNO_CLEAN -j6 universe MAKE_JUST_KERNELS=yes MODULES_OVERRIDE=linuxkpi

With my "sys/conf/kern.post.mk" patch, it passes all the variants.


Is this the expected behaviour or a bug somewhere?
