Make Mac wx use Apple compilers regardless of $CC

If using gcc 4.5 from MacPorts, or probably any other
third party "real" gcc to compile the VM, an unusable
wx-driver was created, as the wx application requires
the apple compilers for all files (not only ObjC)
since we started to support Cocoa wxWidgets.
