s390: remove WARN_DYNAMIC_STACK
s390 is the only architecture which allows to set the
-mwarn-dynamicstack compile option. This however will also always
generate a warning with system call stack randomization, which uses
alloca to generate some random sized stack frame.
On the other hand Linus just enabled "-Werror" by default with commit
3fe617ccafd6 ("Enable '-Werror' by default for all kernel builds"),
which means compiles will always fail by default.
So instead of playing once again whack-a-mole for something which is
s390 specific, simply remove this option.
