This is not a good answer, because it tells you whether the KERNEL is
32-bit or 64-bit, but not the userland.  The kernel could be 64-bit
with the userland being 32-bit.  That is a supported configuration.

The original "file /bin/true" (I've always preferred "file /bin/ls"
myself, since /bin/true has at many times been a shell script) is a
much better answer.
