- work around missing features and bugs in make-3.79.1:
- no order-only prerequisites; incomplete workaround (see comment in diff) - no internal variable MAKEFILE_LIST; workaround - define bar\nfoo:=<long-list> doesn't work; workaround also: - reinstate clean, distclean as noconfig_target. - unconditionally clean libbusybox.so*
