Unfortunately this didn't work everywhere, newer automake don't add
scripts/find-debuginfo.sh to the dist. So I had to push a fixup:

    Makefile.am: Add scripts/find-debuginfo.sh to EXTRA_DIST

This wasn't helped by some of the buildbot workers not yet having
help2man installed (most have now, just the s390x, and ppc64/ppc64le
setups don't have it yet).
