[S390] omit frame pointers on s390 when possible

Always omit frame pointers on s390. They aren't too useful for the
kernel since we have already the kernel stack backchain which allows
us to walk the kernel stack.
So eleminate the extra code for frame pointers. Only allow the extra
code for the function tracer since the gcc compile options -pg and
-fomit-frame-pointer are incompatible.
