Fix: examples Makefiles should pass $(LIBS) at last

Fixes #210

Description

Since Ubuntu 11.10, the "--as-needed" option is given by default to ld
(linker). This option breaks the makefiles given with the userspace
tracing examples. Therefore the libraries against which the program
should be linked should be passed at last:
$(CC) -o $@ $^ $(LIBS)
