You might like to install additional packages before actually running the rpmbuild -bs, but rpm has no way of expressing this kind of "SourceBuildRequires".
By default, rpmbuild -bs fails if BuildRequires aren't present. This suggests that the existing expectation in RPM is that BuildRequires *are* SourceBuildRequires.
