This does not work:

$ make infodocs
make[1]: ./scripts/sphinx-pre-install: No such file or directory

$ make texinfodocs
make[1]: ./scripts/sphinx-pre-install: No such file or directory
make[1]: *** [doc/Makefile:73: texinfodocs] Error 127
make: *** [Makefile:2378: texinfodocs] Error 2

@Tom:
Should we add a build step for each of the new targets to
.gitlab-ci.yml and .azure-pipelines.yml?

Best regards
