(svn r3267) -Codechange: [OSX] universal binary makefile code cleanup

	now PPC code is always compiled before x86 code
	strgen and lng files are only compiled once, which results in shorter building time
	the makefile now assigns default values to undefined values so much less needs to be set up
	the code is now easier to maintain
