This is on 𝐚𝐦𝐝𝟔𝟒. You can have 24𝐓B RAM boxen these days. Assigning 8GB
to a buildd is a configuration error -- it's not about building package X
at home or porting it to a bitty box.

As doko CCed -ports:
With the hat of one of riscv64 porters on: hardware that is deemed
sufficient for buildds has 16 GB RAM and nvme, with very slow CPUs.
Thus, please include riscv64 among LTO archs, barring compiler issues
of course.
Meow!
