Hi all,
this patch changes how old debug information copied from IMPORT_JDK is
treated.
When running the copy_*_jdk target, HotSpot's makefiles copies the
entire IMPORT_JDK folder, including additional files (such as unzipped
debug information). The export_*_jdk targets will then, via the
generic_export target, copy the build artifacts via implicit rules to
the correct destination in hotspot/build/JDK_IMAGE_DIR.
The bug arises when IMPORT_JDK contains unzipped debug info
(libjvm.debuginfo) and the make target produces zipped debug info
(libjvm.diz), or vice versa. hotspot/build/JDK_IMAGE_DIR will then
contain both libjvm.debuginfo and libjvm.diz, but only one of them will
match libjvm.so.
Finally, the JPRT make targets jprt_build_* just zips
hotspot/build/$(JDK_IMAGE_DIR). The zipped JPRT bundle will end up
having different zipped and unzipped debug info, since the IMPORT_JDK in
JPRT contains libjvm.debuginfo and we build libjvm.diz by default.
This patch removes the debug info that we did *not* build. If we build
libjvm.diz, then libjvm.debuginfo will be removed (if it exists).
Correspondingly, if we build libjvm.debuginfo, then libjvm.diz will be
removed (if it exists).

Bug:
https://bugs.openjdk.java.net/browse/JDK-8033580
Testing:
- Building in JPRT
- Building Linux 32-bit locally on a Linux 64-bit machine
- Building Linux 64-bit locally on a Linux 64-bit machine
For all of the above, verify that only the correct debug info is present
in the output.
Thanks,
Erik
