Not sure.
We can re-run the build until it fails (no luck so far), but we don't
have the image.

Before configure the following is run:
(cd config && autom4te --language=m4sh opal_get_version.m4sh -o
opal_get_version.sh)
./autogen.pl --force
Then (in this case):

Commander Vimes didn’t like the phrase “The innocent have nothing to fear,”
believing the innocent had everything to fear, mostly from the guilty but in
the longer term
even more from those who say things like “The innocent have nothing to fear.”
