I should clarify. There's code in toolset.jam which handles per-rule flags.
Moreover, it's only possible to specify flags that apply to a specific rule.
Take a look at toolset.set-target-variable. It takes the name of rule and
looks for the flags specified for it.

To summarize, BB4 is not closed because:
- set-target-variables is kind of copy-paste from V1. I did not think much
about it.
- it does not allow to specify flags that apply to all rules in a module
- we'd need some flags inheritance as we've discussed
