Almost - I debugged a bit and it turns out to be /etc/protocols.  With it the
build succeeds in a chroot.  Arguably we should have it in the chroot, but on
the other hand not having /etc/{resolv.conf,nsswitch.conf,services,protocols}
helps to ensure that builders don't (accidentally) connect to the network.  At
first I thought adns' "make check" tries to connect to the network (which would
be very impure).  But on closer inspection that does not appear to be the case.
