From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

The following shows up on a normal make:

  mv: cannot stat '/work/git/libtracefs.git/lib/tracefs/libtracefs.a': No such file or directory

In order to help with a multithreaded make, the moving of the libtracefs.a
before removing it appears to fix some issues. But now we get a message if
it doesn't already exist. Only move it and remove it if it already exists.

Fixes: 550d8358 ("libtracefs: make the libtracefs.a gen more robust")
