Merge branch 'maint'

* maint:
  Check that sys.config and relup have valid content when added to tar
  Reject systools:make_script if kernel and stdlib are not permanent in .rel
  Don't save child spec for temporary child if child's start func returns ignore
  Generate links in C libraries correctly
