Details:

It looks like we are hitting a bash limit when building the `dist` target on
the default branch. E.g. on the buildbot:
http://buildbot.octave.org:8010/#/builders/21/builds/1281/steps/7/logs/stdio

if test -d "octave-8.0.0"; then find "octave-8.0.0" -type d ! -perm -200 -exec
chmod u+w {} ';' && rm -rf "octave-8.0.0" || { sleep 5 && rm -rf
"octave-8.0.0"; }; else :; fi
test -d "octave-8.0.0" || mkdir "octave-8.0.0"
make[3]: /bin/bash: Argument list too long
make[3]: *** [Makefile:28343: distdir-am] Error 127

The corresponding lines in the Makefile read the following when I reproduce
here:

        @(echo "$(distdir) archives ready for distribution: "; \
          list='$(DIST_ARCHIVES)'; for i in $$list; do echo $$i; done) | \
          sed -e 1h -e 1s/./=/g -e 1p -e 1x -e '$$p' -e '$$x'
