Some more informations on that matter,
a 64 bits process cannot access 32bits address space directly (and
vice-versa), you
need a proxy process for that (example being some 32bits plugins for a 64
bits browser):

Concerning the possible usage of arch triple for target (lib or exe) built
using CMake
and how to define it, I think the work done on Debian Multiarch contains
interesting discussions
and ideas; http://wiki.debian.org/Multiarch

So may be TARGET_ARCH should be a triple as well (including in the Windows
and OS X case)
