While I agree that the fix solves your problems, maybe you could delay 
pushing this for a while?

The regression you noted was not caused by JDK-8201236, but by 
JDK-8198862 "Stop doing funky compilation stuff for dtrace". In fact, 
JDK-8201236 (which is pushed to jdk/jdk but not yet integrated into 
jdk/hs, apparently) will once again remove EXTRA_FILES from the 
SetupNativeCompilation, making zero work again.

So if you just wait until JDK-8201236 moves into jdk/hs, this will be 
fixed. Otherwise, you're just creating a merge conflict for the 
integrator. :(
