disable MN threads on s390s-linux
I check the s390s-linux/Ubuntu system and I found that MN threads
doesn't work with:
* function inlining (-O0 doesn't repro)
* Thread local specifier (`_Thread_local`.
With `pthread_get_specific works)
(it is not an issue of `__tls_get_addr()` written in thread.c)
* swap context with ucontext (coroutine/ucontext)
I couldn't find out what is the root cause of this issue but
disable MN threads to make CI healthy.
