    [S390] Improved kernel stack overflow checking.
    Recent cvs versions of gcc have support for an improved stack overflow
    checking that calculates the size of the guard size for each function.
    If the compiler accepts -mstack-size without -mstack-guard then the
    new stack check is available. We always want to use the new stack
