It should work.  I exclusively use a 64bit openSUSE box.  However, I
have a lot of 32bit packages installed needed for other stuff.

Looking into `gub/cross.py', I see the following comment:

  def setup_linux_x86 (logger, name, x86_cross):
      '''Hack for using 32 bit compiler on linux-64.

      Use linux-x86 cross compiler to compile non-64-bit-clean packages such
      as nsis and odcctools.  A plain 32 bit compiler could also be used,   
      but we do not have such a beast.  Make sure to have 32-bit
      compatibility installed:
          apt-get install ia32-libs
      '''

  [...]

So it seems that you have to add some packages – and the gub
installation instructions should probably be updated, too...
