s390x: add the proper defines for data types

# Don't forget to rebuild sparse with uncommented debug options
# in the Makefile. Also, gcc 3 is known to screw up with the
# cpp macros in the debugging info.


# If a gdb_show_* function is running at a non-zero recursion
# level, only a short summary is shown, preventing further
# recursion. Also note that gdb has only one, global, scope
# for variables, so we need to be careful with recursions.
