Binutils changed something about how it generates symbol tables in
recent versions (newest ubuntu LTS at least). This adds a patch to fix
the resulting error.

This increases build time, and might hurt disk performance for kvm/qemu
a bit. So we disable it by default. But will be useful for docker images
etc.

Remove the ubuntu1804 image. Base only has basic tools, no build tools
or libraries. Install build deps in nopaxos, mtcp, and tas images.

Only builds base image, none of the others.

This speeds up base image build significantly

Just run different scripts inside. This avodis lots of duplication in
the jsons.

This is a lot faster than manually installing from ISO.
