What does this implement/fix? Explain your changes.

• Switches relevant file types to CC from CXX
• Defaults to CC for linking and only switches to CXX if OBJ_FILES_TO_LINK contains a ++ file variant
• Skips passing the ++ LD flags if using the CC for linking
• Removes explicit link to libc++ as the CXX seems to auto-link it when used as the linker
