Okay, I checked the spec for `nativeLinker()`.


     * @implNote The libraries exposed by the {@linkplain #defaultLookup() default lookup} associated with the returned
     * linker are the native libraries loaded in the process where the Java runtime is currently executing. For example,
     * on Linux, these libraries typically include {@code libc}, {@code libm} and {@code libdl}.


So AIX is free to supply a nativeLinker that does not expose any symbols whatsoever, if they do not use dynamic libraries. Then it kind of turns into a test issue anyway, if the tests are written to assume that nativeLinker would return such symbols.

Returning an arbitrary list of hard-coded symbols as is proposed in this PR still seem like the wrong solution to me.
