DESCRIPTION OF CHANGES:
For the clean script, tidied up the standard out.
Several Makefiles had the `@` character in front of remove commands
in the `clean:` or `superclean:` sections. More `@` instances were added.
Some portions of the clean script did not utilize makefiles, and some of
those had `>& /dev/null` to capture the unimportant list of removed files.
The `>& /dev/null` was added to more locations in the clean script.
