RFR: 8347831: Re-examine version check when cross linking

[Henry Jen]

This PR include build changes from @magicus and jlink change to verify the build signature.

Tested with local builds for MacOS and Linux as below shows that cross linking with same build is working while linking with different build failed with error message.
