The SolidRun HoneyComb LX2K is now advertised as supporting
m.2 and PCIe, plus up to 64GB of RAM on a 16-core SoC, which is a
nice ratio between memory and CPU.

I suppose for large-scale rebuilds it ends up being ideal to have
each CPU build one package in a container and not rely on
on spreading out one package across multiple CPUs, but this
needs even more RAM if you want to do the builds in virtual
machines instead of containers.
