* In FreeBSD 14, the prototype of qsort_r() was modified to comply with

* changed, and the comparator function is now taking thunk as its last
* parameter, and both are different from the ones expected by the historical
* FreeBSD qsort_r() interface.
*
* Apply a workaround where we explicitly link against the historical
* interface, qsort_r@FBSD_1.0, in case when qsort_r() is called with
* the last parameter with a function pointer that exactly matches the
* historical FreeBSD qsort_r() comparator signature, so applications
* written for the historical interface can continue to work without
