Changes for intel Mac OSX build

Here are the changes needed to build the servers on an intel Mac.  These have been tested on OSX 10.8.5 (Mountain Lion).

Currently, the only testing done so far is to build the binaries.  A server hasn't been brought up yet.
Also, there is no libEQEmuAuthCrypto.a available at this time, so the loginserver has not yet been built.
