Scrap this explanation. It's accurate, but it doesn't explain what you
are seeing. The reason for the messages you get is that nsgmls is run on
each file separately, so when it sees an xref that's in a different file
it complains. Since nsgmls doesn't do any formatting, just parsing, this
is not a fatal condition, and indeed docbook2man copes with it (via the
manpages.refs file).
I've been working with different makefile rules recently that don't
produce these messages anymore and run a lot faster. I'll commit them
sometime this weekend.
