It's needed on most Core 2 Duos in 10.6 because they run a 32-bit kernel and 64-bit userspace, and Chicken's config-arch.sh just checks the kernel width. `uname -m` on those systems will show x86, but gcc builds x86-64. Later C2Ds (I believe) and all i3/i5/i7 run a 64-bit kernel by default.
I thought on 10.7 that older C2Ds ran a 64-bit kernel, so the issue wouldn't be triggered. However James' experience shows that's not the case, and the workaround is indeed necessary on 10.7.
