/* stat is deliberately hacked to be lstat.
   In src/system.h tar already defines lstat to be stat
   since S_ISLNK is not defined in mes C library
   Hence, we can't use something like #define lstat(a,b) _lstat(a,b)
   to have separate stat and lstat functions.
   Thus here we break tar with --dereference option but we don't use
   this option in live-bootstrap.
