tests/runtime-errors/'stackoverflow.ml' test skips on s390x architecture.

While building OCaml, the configure file that is used, has a case statement that sets the stackoverflow detection macro. But, s390x architecture is not mentioned in the given architectures. I tried manually modifying the case statement in configure file to include s390x architecture, still after build the above mentioned test skips.
Also, how does this feature of stack overflow detection impacts the end user? For instance, does compiler raises error if the program written in OCaml has code that results in stack overflow?
Any help regarding the issue will be appreciated and thanks.
