Remove native compiler dependency in system tests

[llxia]

Native compilation in system tests resulted in many complications when setting up the testing environment.

For example, we need to have the correct compiler installed. xlC is /opt/IBM/xlC/13.1.3/bin (we no longer support it), but it's on the path. xlclang is /opt/IBM/xlC/16.1.0/bin, which isn't on the path. Also, Visual Studio is expected on Windows with specific versions/path.

Talked with @pshipton , and we think we should simplify system tests by removing the native compiler dependency.

ToDo:

• [x] Remove com.test.jlink from system test https://github.com/adoptium/aqa-systemtest/tree/master/openjdk.test.modularity/src/tests/com.test.jlink. If this test is important, we can contribute it to OpenJDK if needed.
• [ ] Move SharedClassesAPI native code into OpenJ9, and stop building it in the tests. https://github.com/adoptium/aqa-tests/blob/9776620cc838d27813365c534a2639a5dced4b92/system/sharedClasses/playlist.xml#L26
• [ ] Ensure we do not have any other native compilation in system tests (i.e., all build-natives-xxx should be empty)
• [ ] ~Inform infra team to remove native compiler as part of the test env setup requirement.~ We still need it for non-system tests.

@annaibm could you take a look at this issue? Thanks

In OpenJDK I see test/jdk/tools/jlink, not sure if we are running these tests.

FYI /opt/IBM/xlC/16.1.0/bin has both xlC and xlclang. OpenJ9 builds no longer use xlC, or 13.1.3 compilers. 13.1.3 is on the path on some machines, but since AIX 7.3 doesn't support it, I expect 16.1.0 is on the path on AIX 7.3 machines.

@llxia Removed the com.test.jlink from the system test com.test.jlink directory and made related build.xml changes that depended on com.test.jlink.

Draft PR: adoptium/aqa-systemtest#498

Had to exclude the following tests as shown in the Draft PR: adoptium/aqa-tests#5992 as the sanity.system test failed for the jlink tests.

Sanity.system test failure (without excluding jlink tests): Grinder #48246

Disabled Tests: (can remove the tests if its not needed) TESTLIST=Jlink_ReqMod,Jlink_AddMLimitM,Jlink_GenOpt

Test run after exclusions: Grinder #48400

Sanity.system test run passed Grinder #48446

I believe we should also remove Jlink_ReqMod,Jlink_AddMLimitM and Jlink_GenOpt from playlist.xml

I believe we also should remove https://github.com/adoptium/STF/blob/03f6cc21c7356c036ccd11173c061417f58b621b/stf.build/include/top.xml#L102

Thanks @annaibm . This issue is completed.
