Removal of the old build system, partial review

[Alan Bateman]

I remember Kelly calling for hazard pay for anyone deleting code and 
triple pay for anyone deleting Makefile code.

At a high level the plan looks reasonable. Aside from build tools then 
what else are you expecting to look at in step 2?

So is the plan to do all of this in jdk8 before RDP2? If so then what 
would you think about pushing the changes to jdk8/tl rather than 
jdk8/build? I suggest pushing the changes to jdk8/tl because you are 
more likely to get more usage and testing before the changes go into 
jdk8. Also it helps to reduce conflicts (the white-spacing and split out 
of CompileNativeLibraries.gmk was disruptive).
