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. Submitted by: Geoff.
