Looks fine, but the generated configure script needs to be generated by 
the script as it also updates a timestamp inside the file. We will still 
need to update the closed version of the generated script in sync with 
this. I will be happy to push both when review has passed if you like.

That looks like a simple typo. Looks good to me. This is in hotspot 
however so will need to go through a hotspot forest and requires 2 
reviewers.

Is the contents of the conditionals for SERVER, ZERO and ZEROSHARK the 
exact same? Perhaps change into one conditional like this?

ifneq ($(findstring $(JVM_VARIANTS), server zero zeroshark),)

I'm also pondering if the build_sa conditional could be made simpler, 
but this is planned to go away before JDK 9 is done so I'm ok with 
leaving it like this.

Build changes go directly to jdk9/dev. The build-infra forest is for 
prototyping things for the build-infra project and has no scheduled 
pushes to jdk9. Perhaps it would be better to combine the above changes 
with your source changes and submit reviews separately for hotspot and 
root/jdk repos instead?
