Compile failure on armv7a

Hi, I'm trying to build PyCoral with Tensorflow 2.7.0 for arm7a and it fails as follows:

$ git clone https://github.com/oberluz/pycoral.git
$ git checkout 2_7_0
$ git submodule update --init --recursive 
$ DOCKER_CPUS="armv7a" ./scripts/build.sh --python_versions "310"

...

Building for other versions of python (36 37 38 39, see scripts/build.sh) words. But it fails for 310 which uses ubuntu 22.04

Any ideas?
