What I have done in similar situations [1] is applying rpm's
--with/--without in combination with koji scratch builds and local
builds.

I.e. I am using %{?_with_XXX} and friends inside of specs, such that you
can specify them on rpmbuild's command-line for manual local builds. 

For chrooted "non-production/test-builds" (e.g. koji scratch-builts) I
edit the spec (adding %define _with_XXX <something> to the top of the
spec).

A better approach probably would be to have way to pass
rpmbuild-parameters to koji/mock for scratch builds.

[1] In my case primarily testsuites which require network access (N/A in
mock) and/or packages which are not part of Fedora.
