I tried to find everything relating to HP-UX, aCC, ia64 and hppa.  Or
do you still want to keep the hppa bits for NetBSD (I wasn't sure if
your threat to set up a NetBSD/hppa system was affected by the
hardware failure you mentioned)?  Or just leave it in there in
orphaned hall-of-fame state, like m68k, m88k, Vax?
