They are (IMHO) very confusing to implement. However have a look at a
the libvirt spec file for a working example:
Also there's a bug open to make these flags work from 'fedpkg local':

Yeah I don't understand this either. I didn't know it was possible to
submit an SRPM directly (except for scratch builds), and if there is
it doesn't sound desirable.

There isn't .. and shouldn't be, since you'd want 'fedpkg build' to
build exactly one RPM variant.
However for 'fedpkg local' these flags could be pretty useful, see
