Log:
  Correct module symbol export handling
  
  EXPORT_SYMS can be set to YES, NO, a list of symbols to export from a
  module, or to a filename containing such a list.  For the case that it
  is set to a symbol list, replace spaces in the list with newlines, so
  the created file is in the format expected by kmod_syms.awk.
