It looks like the test failures were cause by bug #848339, which was
fixed in libunbound2 1.6.0-2. Relevant log excerpts:
Setting up the build environment (libunbound2 version):
> Selecting previously unselected package libunbound2:amd64.
> Preparing to unpack .../088-libunbound2_1.6.0-1_amd64.deb ...
> Unpacking libunbound2:amd64 (1.6.0-1) ...
Test log (look at any of the failed tests):
> gnutls-cli: symbol lookup error: /usr/lib/x86_64-linux-gnu/libunbound.so.2:
> undefined symbol: fake_dsa
I believe a rebuild with libunbound2 1.6.0-2 will fix the test failures.
However, there were also build failures on the 32 bit architectures,
which are my fault for not using the right (portable) format modifier
with apr_size_t in a few calls to ap_log_error() or apr_psprintf(). I
didn't get to test a 32 bit build yet, but I believe the attached patch
will fix the problem.
