Yep, indeed, worked!
SRC=/usr/src
OBJ=/usr/obj
cd ${SRC}
make TARGET=arm TARGET_ARCH=armeb TARGET_CPU=xscale buildenv
# There is check ${PATH} to have toolchain in that dirs
if [ ! -x ${OBJ}/${TARGET}.${TARGET_ARCH}/${SRC}/tmp/usr/bin/cc ]; then
make kernel-toolchain
fi
# Or just do make -DNO_CLEAN kernel-toolchain
cd sys/modules/module/you/need
make
Thank you John-Mark!
