The only 3.0.x version available for x32 is 3.0.0-1, because newer
versions build-depend on pmix, which in turn build-depends on pandoc,
which is unavailable there.  (I think the Haskell stack generally is.)
With that version installed in my laptop's x32 chroot and everything
else left at the versions available in unstable, I get *different*
errors per the attached log, excerpted below.  (Using unstable across
the board yields the same errors as on the autobuilder.)

  13/24 Test #13: MdrunUtilityMpiUnitTests .........***Failed    0.02 sec
  --------------------------------------------------------------------------
  There are not enough slots available in the system to satisfy the 4 slots
  that were requested by the application:
    /home/amu/src/gromacs/gromacs-git/build/openmpi/bin/mdrunutility-mpi-test
  
  Either request fewer slots for your application, or make more slots available
  for use.
  --------------------------------------------------------------------------
  [...]
  The following tests FAILED:
  	  9 - GpuUtilsUnitTests (Timeout)
  	 13 - MdrunUtilityMpiUnitTests (Failed)
  Errors while running CTest

I can retest on a more powerful system if you think that's likely to
make a difference; I just didn't yet have an x32 chroot there at all,
and would need to reboot it to enable the necessary kernel parameter
(syscall.x32=y).

I hope that information helps!
