This bug report sounds absurd to me but I don't see anything else
obvious that changed. I reconfigured with (kernel linux-libre) and the
gpg-agent couldn't find any pinentry. I even tried killing gpg-agent and
manually launching it and giving it the path to pinentry. I then changed
to (kernel linux-libre-5.7) and used the same commit to reconfigure and
gpg-agent started working as expected again.

I added and removed the qemu-binfmt-service-type before the first
failure with 5.8 and after 5.7 worked. I've attached my os config, and
here's a link¹ to the repo.
