  Ok for master?

---

Fixes compile warnings like:

.../newlib/libc/reent/getentropyr.c: In function '_getentropy_r':
.../newlib/libc/reent/getentropyr.c:48:14: warning: implicit declaration of function '_getentropy'; did you mean 'getentropy'? [-Wimplicit-function-declaration]
   48 |   if ((ret = _getentropy (buf, buflen)) == -1 && errno != 0)
      |              ^~~~~~~~~~~
      |              getentropy
