Good to see that this has been discussed before.
IMHO the sanest thing would be to make build-{arch,indep} goals
mandatory. It would make build-arch target useful for buildds and is
the most robust and simplest of the solutions I've seen so far. An
added benefit would be to have all the build targets be symmetrical
with the binary targets.
The obvious con of the change would be the transition required. But,
as the effects of the change would only touch infrastructure invisible
to users, I don't see a need to set any deadlines for this transition
to happen. I'd propose the following change, let the transition
happen on its own pace, and if it ever seems to be close to
completion, change the policy to reflect that.
IMHO that last "must" part would be justified too. There's no robust
way of checking for the targets' presence right now.
Would there be a need to state explicitly that packages may implement
build-{arch,indep} by depending on build target? The main issue is to
get those targets in there, not to optimize builds for every package.
