rpmbuild may not download the source code if disable_source_fetch is defined.

In the deployment/rpm/about.md file the documentation states to run:

rpmbuild -ba hello.spec

If deisable_source_fetch is enabled/true, rpmbuild may not automatically download the source from ftp.gnu.org unless the

--undefine=_disable_source_fetch

parameter is set. I recommend updating the documentation so that the source tarball is downloaded.

rpmbuild -ba --undefine=_disable_source_fetch

the setup section on the same page explicitly states wget http://ftp.gnu.org/gnu/hello/hello-2.10.tar.gz, which is the way the sources are retrieved here.
