sysutils/logrotate 3.8.8 causes a segmentation fault.  SVN r450 upstream
introduced sortGlobResult, which uses qsort_r.  Linux and FreeBSD have
different implementations of this function:

Linux:
     void qsort_r(void *base, size_t nmemb, size_t size,
                  int (*compar)(const void *, const void *, void *),
                  void *arg);
FreeBSD:
     void qsort_r(void *base, size_t nmemb, size_t size, void *thunk,
                  int (*compar)(void *, const void *, const void *));


Note differences in location of thunk/arg and compar function pointer. Proposed
patch attached.
