[Linux] Add armhf build.

Some modules are disabled due to incompatibilities:
- raycast (embree), we should fix detection in module config.py.
- etcpak, this likely also require at least aarch64 instructions to build.
- denoise (oneDNN), also needs fix in config.py (x86_64 only).
- theora (are we keeping this?).
