Reorder forkbomb build so ./ gets built first. Then toybox utilities can be used to extract all the other packages (patch, bunzip, sha1sum, echo, eventually tar...) Motivated by a bug I encountered in gnu patch on Kubuntu 7.10 that's insisting linux-2.6.13-cmdline.patch is a reversed patch, when it isn't. (That patch has been happily applying for over a year now, and I examined it by hand. The bug's in the Ubuntu patch command. Not my problem.)
