It was -O2 because your email said -O2. Only thing that changed in the 
command line(s) was the compiler binary path/name.

Tarball of the newly built stuff attached, the other stuff should be at 
http://landley.net/simple-root-filesystem-i686.tar.bz2 (which isn't the 
release version because I made sure this one _wasn't_ built from a stage 
2 cross compiler. This is from an aboriginal build that didn't do a 
stage 2 cross compiler, but built everything with the "simple" cross 
compiler.)
