Remove conditional linking of libraries

[midronij]

If a library is needed by any compiler, it should be used for all. Thus, this contribution removes the AIX && OPENXL condition that is used to add several extra libraries to j9vrb.

[midronij]

@dsouzai here's the change removing the conditions from the list of linked libraries. It shouldn't depend on either of the other OpenXL PRs (#20690 and eclipse-omr/omr#7561).

Skipping z/OS and Windows because there aren't any build machines up for those platforms

Oh, I've been trying to use an OMR Jenkins command 🤦

Jenkins compile all jdk8,jdk21

Build failures on x86-64 Mac and Linux:

CMake Error: The inter-target dependency graph contains the following strongly connected component (cycle):
  "constgen" of type EXECUTABLE
    depends on "j9util" (weak)
    depends on "j9stackmap" (weak)
  "run_constgen" of type UTILITY
    depends on "constgen" (strong)
    depends on "constgen" (strong)
  "j9stackmap" of type STATIC_LIBRARY
    depends on "j9util" (weak)
  "j9util" of type STATIC_LIBRARY
    depends on "j9stackmap" (weak)
    depends on "run_constgen" (strong)
At least one of these targets is not a STATIC_LIBRARY.  Cyclic dependencies are allowed only among static libraries.
CMake Generate step failed.  Build files cannot be regenerated correctly.

It seems the windows builds will time out for lack of build machines, even though clicking on the label ci.role.build&&hw.arch.x86&&sw.os.windows seems at first sight to show two machines online. On closer inspection, both of those are "being launched"

@midronij, this change is causing a build error on Linux and Mac, but for some reason only on x86-64

And as with #20690, I can't tell about Windows or z/OS

[midronij]

I'll try and run a build manually for Windows and z/OS as I did for #20690. And of course, I'll take a closer look at the x86-64 failures as well.
