I did that on purpose, because adding the actual server certificate to the
chain does not change the outcome, and I wanted to strip down
the test case as much as possible.

That should be correct, it's not a host certificate after all.

No, that does not work either. Here is a host certificate:
bash-4.0$ openssl x509 -noout -text -nameopt oneline,-esc_msb,utf8 -certopt
no_pubkey,no_sigdump -purpose -in host_certs/handy-thomas.pem
Certificate:

I concatenated the intermediate signing certificate with this one to form the
server certificate, and performed verifcation of the
resulting chain. Here's the result:
bash-4.0$ cat cacert/host_ca.pem host_certs/handy-thomas.pem >/tmp/test.pem
bash-4.0$ openssl verify -x509_strict -CAfile cacert/root_ca.pem -purpose
sslserver /tmp/test.pem
