The problem is that I key off the target host string to decide what
assembly to use for the atomic operations. For most 64 bit
platforms, the architecture string is the same for 32/64 bit and then
you use sizeof(long) to determine whether to use 32 or 64 bit
instructions. So what I need to add to the configure script is a
check if we're on x86_64 that if sizeof(long) == 4, we use the
assembly for x86, not x86_64.
