that's actually not quite true, it only fails on amd64 in our setup, but
builds nicely on i386 and armhf! eg check
https://tests.reproducible-builds.org/rb-pkg/unstable/i386/ocrmypdf.html

no. Also: our amd64 and i386 setup are pretty much identical…

…except that i386 uses an ext4 filesystem for the pbuilder workspace,
while amd64 uses a tmpfs filesystem. 

(There are more variations between amd64+i386 (cpu type is varied on
amd64 but not yet on i386, OTOH there is 32+64 bit kernel variation on
i386, but not on amd64…)

done.
