The benefit is that if you learn one of the Makefiles, you can quickly
pick learn the other one ;)

Yep, agree, and looking at jdk/test/Makefile, it does things slightly
different. When running one of jtreg groups jdk_*, core_* or svc_* via
the top-level Makefiles, then the results will end up in:

  <top-level>/build/<conf>/testoutput/<jtreg-group>

Given the current feedback, the proposed change is to put the hotspot
results in:

  <top-level>/build/<conf>/testoutput/hotspot

We could align jdk/test/Makefile and hotspot/test/Makefile by having the
hotspot results in <top-level>/build/testoutput/<jtreg-group> as well.
The jtreg groups with identical suffixes are already prefixed by their
folder (e.g. jdk_svc, hotspot_svc), so there shouldn't be any name
clashes.

I will send out a new patch soon.

Thanks,
Erik
