Changes to file(1) for FreeBSD:

- 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.
