NetBSD's man is unusual in that it doesn't understand an empty $MANPATH component as "the system man path", and doesn't have a `manpath` or `man --path`. It has a `-m` option that would be useful, but other mans also have a `-m` option that isn't, so detecting it is tough. It does have a `-p` option that almost does what one would want here, so we hack around it to make things work. Fixes #5657. [ci skip]
