This might explain it:

The mmapped local-archive contains all languages even though only the
ones you use are accessed from it. Other distros split them and the
installers only install what you want.

That's an interesting difference on its own, since the underlying
files are about 95M and 54M respectively. Does the 32 bit kernel use
some tricks to sparsely map files where the 64 bit one does it
directly with page tables?
