This was cd ${SYSROOT_DESTDIR}${KERNEL_SRC_PATH}/scripts in my patch but I will test out this one too.
but this is ok since 

ifeq ($(KBUILD_EXTMOD),)
# Additional helpers built in scripts/
# Carefully list dependencies so we do not try to build scripts twice
# in parallel
PHONY += scripts
scripts: scripts_basic include/config/auto.conf include/config/tristate.conf \
         asm-generic
        $(Q)$(MAKE) $(build)=$(@)
