* Link separate JSystem libraries due to control.cpp This allows the Xcode generator to work, otherwise it breaks on the duplicate control.o files within the game_debug library. * Fix __memcpy define on GCC * Try LINK_GROUP:RESCAN for GNU ld * Combine dusk/game_base/game_debug targets * Fix compile defs syntax
