Subject: [PATCH 1/2] trace-cmd: Makefile - link all trace-* objects into ctracecmd.so

Got a few undefined symbols when using the Python interface to trace-cmd,
the first one was:

root@...ezy:~/trace-cmd# python tracecmd.py
Traceback (most recent call last):
  File "tracecmd.py", line 22, in <module>
    from ctracecmd import *
ImportError: /home/andi/working_git/trace-cmd/ctracecmd.so: undefined symbol: get_file_content

linking the objects that contain those symbols fixes the problem.
