[S390] remove redundant stack check option
Newer gcc versions offer an architecture-independent option to check the stack size and warn if it reaches a certain limit. This option already existed for s390 by using -mwarn-dynamicstack. Since one stack check option is enough remove the s390 specific stack check but keep the option that warns about dynamic stack usage because that is not covered by the generic option.
