Was made:
apt update
apt upgrade

Start by reproducing `make` in `/home/biqu/klipper` and read `Makefile:83` together with `scripts/buildcommands.py` at lines 140 and 168. Trace the request handled by `decl_initial_pins`; done means the build completes without the `ValueError` while generating `out/compile_time_request.o`.
