Since trace-read.o is now linked into the python library, the global
variable silence_warnings and show_status (defined in trace-cmd.c for
trace-cmd) used in trace-read.c are also defined in the swig interface.
This way the two variables are exposed to python as
tracecmd.cvar.silence_warnings and tracecmd.cvar.show_status .
If this is not done, running tracecmd.py will fail due to undefined
symbols:
root@wheezy:/home/andi/working_git/trace-cmd# python tracecmd.py
Traceback (most recent call last):
File "tracecmd.py", line 22, in <module>

ImportError: /home/andi/working_git/trace-cmd/ctracecmd.so: undefined symbol:
