It's the bit-ness of the binary itself.

For the opensmalltalk-vm VMs, this amounts to the same thing, although
in theory the image word size could be independent of host word size.
But in any scenario, you don't want to mix 32-bit and 64-bit executable
files in the same /usr/local/lib/squeak/<foo> directory, so the simple
check for sizeof(void *) should serve for the forseeable future.

As an aside, in the interpreter VM a similar installation naming
convention is used, but in that case it refers strictly to image
word size regardless of host word size. Thus the naming conventions
are similar, but they actually mean different things on opensmalltalk-vm
compared to squeakvm.org interpreter VM. But for now that difference
does not matter.
