For jdk8u building Windows --with-native-debug-symbols=external is missing
debug symbol files in the debug image.
Also, on other platforms the image jre/bin folder contains .debuginfo files for executables that are not in jre/bin.

https://bugs.openjdk.java.net/browse/JDK-8252395 fixed the other platforms, however the change did not fix
the Windows path, it also did not remove the non-jre/bin debug files correctly.
