Hack way to compile freeradius causing freeradius to hang under multithread mode

[Ming-Ching Tiew]

OK I will try to debug and see :-

As the first cut, 'netstat -naut' shows that there is no listening
on port 1812, whereas when it's working there is something listening
on port 1812. 'radiusd' will daemonized, but it must be blocking at 
thread creation or something.
