(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
