RFR: 8352692: Add support for extra jlink options

Mon Mar 24 10:42:26 UTC 2025

Please review this simple change to allow for extra `jlink` flags to be passed to the JDK build by `configure`. The bug describes use-cases where this would be needed.

Testing:
- [ ] GHA (currently running)
- [x] Manual tests with a fix for [JDK-8352689](https://bugs.openjdk.org/browse/JDK-8352689) together with a `jlink` arg file.

Thoughts?
