I always wondered why re-running make on a criu checkout always prints out GEN magic.py even if no file has changed. It seems the Makefile was looking for the file in the wrong location. Providing the full path to the file will now only rebuild magic.py if something actually changed that requires a rebuild. Signed-off-by: Adrian Reber <areber@redhat.com>
