META_MODE+filemon: Default -DNO_CLEAN enabled.

Browse Source 
When using meta mode with filemon, the build is reliably incremental
safe.  Bmake will use the meta files, along with filemon information,
to rebuild targets when their dependencies change, commands change,
or files they generate are missing.
