Linux: allow cross compiling the 32bit viewer on a x86_64 platform

to do so: (have anything for crosscompiling installed),
  export WORD_SIZE='32'
before configuring and/or building.
Be aware: Mixing several platforms in one root directory probably wont work (didn't try though).
Cross compiling the 64bit viewer on a i686 platform isn't tested, but probably will work using export WORD_SIZE='64'
