RFR: JDK-8315278: Patch 'print-targets' target to print targets separated by new line

Wed Aug 30 03:18:26 UTC 2023

Currently 'make print-targets' print all targets on the same line separated by space. That isn't only terribly to read but hard to "grep". Printing each target on a separate line seems much better.

Tested on: Linux x64, Windows x64 and MacOS AArch64
