> Building Asterisk on NetBSD currently fails as {{gethostbyname_r}} is incorrectly detected as being present:
> {code}
> utils.c: In function 'ast_gethostbyname':
> utils.c:234:11: warning: implicit declaration of function 'gethostbyname_r'; did you mean 'gethostbyname2'? [-Wimplicit-function-declaration]
>   result = gethostbyname_r(host, &hp->hp, hp->buf, sizeof(hp->buf), &herrno);
>            ^~~~~~~~~~~~~~~
>            gethostbyname2
> utils.c:234:9: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
>   result = gethostbyname_r(host, &hp->hp, hp->buf, sizeof(hp->buf), &herrno);
>          ^
> {code}
> On NetBSD, {{gethostbyname_r}} is an internal libc symbol that is not exposed in system headers and that is incompatible with other implementations.
