ええと、すくなくとも本日の ruby_native_thread_p() は yesになっていますね。
mkmf.logを下に pasteします。
他に問題があると言っているのではなく、最近のいくつかの修正で挙動が
変わっているようです。ちゃんとbisect出来ていませんが。

現在はこのコミットをrevert しても現在は動きます。よって不適切なコミットなのであれば
（文面からはそれっぽいですが）、逆変更コミットをしていただけないでしょうか？

また、修正した身に覚えがないということであれば、多少時期が遅くなっても
よいのであれば bisect 調査に協力できます。

よろしくお願い致します
