Ciao @accuminium, I am closing this PR. I made some major modification to the hero-gcc-toolchain https://github.com/pulp-platform/hero-gcc-toolchain/pull/6 which I would like to integrate into this PR.

This will require a bit of spinning to test the new builder scripts and this branch it is already too much squashed...
