I received lots of explanations and good advice. Thanks to:
TW = "Tracy J. Di Marco White" <firstname.lastname@example.org>
TL = Ted Lemon <email@example.com>
MH = "Michael L. Hitch" <firstname.lastname@example.org>
JS = Jonathan Stone <jonathan@DSG.Stanford.EDU>:
Here some particularly helpful extracts from the conversation:

I think I can manage to change the Makefile by myself :-), but I must
admit that I have little experience with assembly language, none
recent, and none at all for the MIPS chip. (6502, anyone?) Could you
post your diffs or explain where I should add ".abicalls"?
(BTW, I eventually got a clean compile on a stock NetBSD 1.2 system,
without libwrap, but I'd like to do this "right", and maybe learn a
thing or two in the process.)
