Probably because the core is 32-bit little-endian.  Anything larger than
that is synthetic, and subject to someone writing crappy, nonportable
code to implement it.  Of course, you can always fsck it up with smaller
word sizes too.

ARM machines can be either big-endian or little-endian, but they usually
aren't dynamically configurable the way some MIPS machines are.  "ARM"
vs. "ARMEL" is mostly about parameter passing conventions, I don't think
it's likely to address your problem.
