Truncate size of Docker images, stop storing temporary compile-time files

[oleg-nenashev]

Images are extremely big, especially librecores-ci-riscv.
We need to cleanup them a bit

I am not sure what the current aims are with the riscv image but if riscv-gnu-toolchain is there just for compiling binaries and not testing riscv-gnu-toolchain itself then these prebuilt toolchain could be used

@wallento any comments
please also add this to Dockerfile

ENV PATH = "/opt/riscv/bin:${PATH}"

Hi,

I think this part should be the target of more consolidation:

• We should have one OSS container with pre-built snapshots

• It is worth considering the tools-based flow for those.

Overall, reminds me to write up a summary of all options and work-in-progress.

Cheers,
Stefan

Hi, the images here are getting replaced.

This one is the proper replacement: https://github.com/lccidocker/osstools
