This is more of a Haskell problem than an earlyoom one. Pandoc seems to not like 32 bit. If you take a look at the CI, there are no successful builds.
http://ci.guix.gnu.org/search?query=earlyoom%20system:i686-linux&border-low-id=145628 Maybe the documentation related phases should just be deleted on 32 bit, or it could be a separate package, or something.
