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
it needs both PPC and x86 libs to compile
due to this fact, compilation with libPNG or SDL is not tested (dedicated servers only)
only PPC part is tested as I don't have x86 OSX
This is not a fix for the issues with static linking, more like a workaround. Static linking still got issues
Apple recommends to use dynamic linking anyway, so I guess this doesn't matter much
