Packages that use dynamically generated BuildRequires can't be built with "fedpkg local" out of the box.

Would it make sense to print an error when attempting to build a package that uses %generate_buildrequires instead of failing hard with missing dependencies?

Or would it be possible to use the generated buildreqs.nosrc.rpm `with "dnf builddep" to install the missing dependencies and then continue with a "real" build?
