@magicus @erikj79 it's now clearly stated that you want everything under `make` owned by the build team, which is fair.  You are right that `make` has been easily considered as a dumping ground and it's time to define a clean structure.

I reviewed this patch and this looks okay to me.   Some follow-up questions and follow-on cleanup for example "should jdwp.spec belong to `specs` directory vs `data`?  There are platform-specific data (such as charsets) which has been special-case in the makefile and they need follow-on clean up.   I agree that this should be cleaned up by the component teams and not part of this PR.
