When using a cross compiled jdk, only class list is generated:


checking if the CDS classlist generation should be enabled... enabled, from default 'auto'
checking if CDS archive is available... no (not possible with cross compilation)


Using a cross compiled jdk on hardware/qemu-system same tests fails, the issue is not related to running inside qemu.
I think the require tag is to coarse - as I think we have two cases:
- The JDK have a full CDS archive
- The JDK can generate a CDS archive

Not sure what to do.
