Making a pytorch wheel for armv7

I have a Raspberry Pi Compute Module 3 and would like to run pytorch (cpu only) on it. I tried following this guide, but I don’t have enough space left on the device to increase the swap, so the compiling just freezes along the way…
But I had an idea of building a pytorch wheel made for arm. I downloaded the rpi toolchain and set the compiler flag to

export CC="/home/me/gits/rpi_tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc"

I also set cuda and no distributed to false

export NO_CUDA=1
export NO_DISTRIBUTED=1

but when I tried running

python3 setup.py sdist bdist_wheel

I got gcc error saying
