RFR: 8017480: Move copying of jfr files to closed makefile

[David Holmes]

Erik,

Thanks for fixing this in this way - much appreciated.

One thing I want to flag. In hotspot we have to add .PHONY entries for 
all files that we might -include, otherwise make tries to create them by 
executing a bunch of implicit rules, one of which triggers premature 
execution of the precompiled headers logic.

Now the main build may not have this problem, but I would think make 
wastes a lot of time attempting to build a missing include file when we 
don't want it to even attempt that. So the .PHONY should improve 
performance.
