Buildroot policy scripts run before %doc processing

[fweimer-rh]

As far as I can see, %doc processing after %{___build_post}, so build root policy scripts do not see any documentation files.

This makes it impossible to use buildroot policy scripts to unbundle web assets found in documentation, for example.

The "special %doc" is indeed very, very special.

Build root policy applies to files installed by %install stage, the %doc processing occurs much, much, much later. Changing this would probably be very difficult due to the way the special %doc and %license processing is tied to %files section processing. And, who knows what it doing so would break because this has been the case for closer to 30 years now.

Maybe it'd nowadays be (more) feasible to have eg %install specific macro that does something similar to what the build-in %doc does, but from %install. But no such macro exists now.

For existing rpm's, the only way to get brp-scripts to process documentation is to install the docs in %install stage.
