Or, if it's anything like the various versions of the 970 ('G5' in
apple speak) the kernel will refuse to build unless you set it for
64-bits (and have a 64-bit (cross-) gcc (C only) and binutils.
I've done that in the past for ppc (32) userspace on ppc64. Some
packages in the base system may produce obscure issues doing that,
so not all of my builds succeeded.

Dunno about the usage analysis (a lot of us build our own systems
"because we can" or "because it's there"), but research is
definitely needed. 'linux32' can be helpful if configure thinks
it's on a 64-bit machine.
As was said earlier, clfs might be (a little) more useful - I'm not
willing to talk about the detail here, it's definitely O/T (we
haven't even got x86_64 into LFS yet).
For a machine with only limited memory, I guess building a 32-bit
userspace is probably a lot more practical than 64-bit (e.g. the
toolchain packages build much bigger files on 64-bit powerpc than on
x86).
