It does seem like newer versions do have it:
https://sourceforge.net/p/mingw-w64/mailman/message/34765722/
https://sourceforge.net/p/mingw-w64/mingw-w64/ci/master/tree/mingw-w64-crt/misc/_configthreadlocale.c

We could just refuse to support thread safety on mingw if that's not
supported? Or is that too aggressive?
