Committed By:   rillig

Modified Files:
        src/usr.bin/make: main.c

Log Message:
make: document the guard for directories in unlink_file

Document only the POSIX requirement for now, as I didn't find
information about _which_ ancient UNIX systems would corrupt the
filesystem on unlinking a directory.

http://man.cat-v.org/unix-1st/2/sys-unlink (1971) says:
> It is also illegal to unlink a directory (except for the super-user).
