      [libcxx] Re-include <osreldate.h> in __config for FreeBSD
    
      In 0a97720d0197 some changes were made to `__config` for assuming that
      `__BYTE_ORDER__` is always present.
    
      However, this deleted a `<osreldate.h>` include for FreeBSD, which is
      required to get the value of `__FreeBSD_version`, and that is used later
      in the file to determine whether `_LIBCPP_C_HAS_NO_GETS` needs to be
      enabled.
    
      Include `<osreldate.h>` just after the other includes used for feature
      detection, to fix this.
    
      Note that when FreeBSD 13 is EOLed, this can be removed, as then all
      supported FreeBSD versions will no longer have `gets()`.
