I just briefly looked into the webrev. I think the "usual" place to do these adjustments is
JvmOverrideFiles.gmk, on per-file basis. We did it for Shenandoah, and there are also plenty others:

Also note it makes sense for "release" builds only? In Shenandoah, we used to do this for all build

compilation/linkage times.
