BIND8, BIND9 static compilation problems

[Mark_Andrews at isc.org]

	Glibc contains a weak references to handle the differences
	between threaded and non-threaded builds.  BIND 8.4.2
	contains a work-around.

lib/irs/irs_data.c:
#ifdef _REENTRANT
struct __res_state *
__res_state(void) {
        /* NULL param here means use the default config file. */
        struct net_data *net_data = net_data_init(NULL);
        if (net_data && net_data->res)
                return (net_data->res);
 
        return (&_res);
}
#else
#ifdef __linux
struct __res_state *
__res_state(void) {
        return (&_res);
}  
#endif
#endif

> This didn't help either: export LDFLAGS=-static 
> export CFLAGS="-static -static-libgcc".
