From: Namhyung Kim <namhyung....@lge.com>
If an user gives both of --symfs and --vmlinux option, the vmlinux
will be searched under the symfs directory. This is somewhat
confusing since vmlinux often lives in kernel build directory or
somewhere other than user space binaries.
So it'd be better not adding symfs prefix for a vmlinux if it has an
absolute pathname.
