On macOS x86_64 I saw in our CI those tests failing when enabling the
dead_strip feature
serviceability/sa/ClhsdbCDSCore.java
serviceability/sa/ClhsdbFindPC.jav
serviceability/sa/ClhsdbPstack.java
(and macOS on Intel is not that interesting any more these days)
For macOS aarch64, the tests in our CI were fine but I see some failures in the
GHA in the serviceability area.

Have to check why I do not see those issues in our test infra.
