Comment:

 It's interesting to note that this is not only restricted to profiling and
 non-profiling but crucial for cross compilation. It becomes more and more
 obvious to me that profiling and cross compilation seem to share a fair
 bit of preferred infrastructure.

 In the cross compilation setting the plugin database would have to hold
 packages compatible with the host, while the regular target database would
 hold packages for the target platform.

 Therefore I'm not certain this is or should be restricted to profiling
 /non-profiling only. I'm also uncertain if it would make sense at some
 point to have more than two package databases? What if I want to allow
 multi-target support down the line, would I need package databases for
 each target, or should they live in one package database and can share the
 interface files while having different object files? I somewhat doubt that
 would be practical generic solution due to cpp and architecture
 differences?
