Corrected some bogus cross references to man pages that we don't/won't
have and either deleted them, or found a more appropriate man page
that we do have. Various other minor changes to silence manck.
Manck is currently down to about 200 lines of errors, down from
the 500 - 600+ when I started all this.
- Makefile: bmake the sucker
- file.1, magic.5: replace __MAGIC__ and __SECTION__
- add Magdir/freebsd
- add file to usr.bin/Makefile
A note on the FreeBSD magic entry:
The magic number "000000407" is reported as "impure format". This
stops file(1) telling us that our object files are "PDP-11 executables".
(Saying anything more than "impure format" would probably be bogus.
