This is not consistent with what you posted before. Looking again, the old configure output you posted has: checking for gettid()... yes note the (), which is only possible if you haven't re-run buildconf. Re-run buildconf and configure, and if the build still fails please provide the full config.log somewhere so I can try to understand what's going on.
