Dht11 driver compilation issue

Hi
I followed below link for compiling DHT11 driver.

https://developer.toradex.com/knowledge-base/build-u-boot-and-linux-kernel-from-source-code

I downloaded kernel from following link ,

git clone -b toradex_4.9-1.0.x-imx git://git.toradex.com/linux-toradex.git

I exported cross compiler with this command,

. /usr/local/oecore-x86_64/environment-setup-armv7at2hf-neon-angstrom-linux-gnueabi

Then created .config file with this command ,

make colibri_imx7_defconfig

After that i tried to compile the kernel by running following command,

make -j3 zImage 2>&1 | tee build.log

After running command it gives following error log, attached in txt file

What i am missing here…

Thanks,
