The best solution is to add that function to the gthr API, but stage1 is about
to end, so we might not have time to do it (the reason for the _S_destroy hack
in the first place was lack of time to fix it properly, see PR 46455 comment
19)

Is it possible to extend the _S_destroy hack to handle your case?

N.B. this is not a libstdc++ bug, gthreads is not part of libstdc++ (or we'd
have just changed it to fix PR 45455)
