Sorry, looks like I forgot to update the man page when I added this!

Mainly because:

(a) I didn't think of just specifying the versioned-OS without the
    machine architecture and didn't have a need for that,

(b) I did have a need for the full syntax in pkgsrc cross-builds and I
    wanted to make the criterion for recognizing the full syntax
    simple so it would be low-risk to adopt.

But it would probably be reasonable to look for a space instead of a
slash.  Also it looks like when I fixed one instance of strchr abuse I
didn't fix the other for some reason, oops.  I think a patch to add
the versioned-OS syntax would be fine (and a fix for the strchr
abuse).
