Well, we shouldn't use optimisation (-O3) during buildworlds as it's not recommended. On the oposite side, we should try to produce the optimisable source code.
The problem you hit is that the pthread stub functions as declared within src/lib/libc/gen/_pthread_stubs.c are optimized-out by "-O3" causing undefined symbol errors later during build. I don't know if it is gcc's optimiser bug or there is something wrong with _pthread_stubs.c code, but someone who knows should report and/or repair it.
