Found a RPiB3+ lappy kit::


https://www.techrepublic.com/article/pi-top-review-a-raspberry-pi-laptop-for-tinkering-on-the-go/

Now just add a carrier board for (4-8) RPiB3+ and cluster them together.
Several web sites indicate that distcc can be use to compile native code
for these Broadcom based arm64 systems::

"The project's GitHub page additionally contains instructions for
setting up crossdev and distcc to build for the 64-bit RPi3. "
