Aha, OK, I'm hitting the menuconfig/sstate bug. By bumping the PR I was
able to get real numbers.

-rwxr-xr-x 1 dvhart dvhart 561828 2012-06-15 15:52 /home/dvhart/busybox-r8-sci
-rwxr-xr-x 1 dvhart dvhart 559268 2012-06-15 15:54 /home/dvhart/busybox-r9-i

So the delta for including SETSID and CTTYHACK is 2560 bytes.

The patch comment in the branch has been updated accordingly.
