Our HEAD does work on that NetBSD installation. I can try this
patch, but it'll take an hour or two to get results ... stay tuned.

I'm not sure about the __hppa vs __hppa__ thing. If we're assuming
that NetBSD is the only remaining hppa platform of interest, then
clearly only one of those is needed, but I don't know which one
should be preferred. It appears that both are defined on NetBSD.

(FWIW, I know that OpenBSD works on this machine too, or did the
last time I tried it. But it probably has the same opinions
as NetBSD about predefined macros.)
