Yeah, so as I see from GHA testing:


STARTED    ArchTest::checkParams '[8] ppc, PPC32, 32, BIG_ENDIAN, false'
java.lang.IllegalArgumentException: No enum constant jdk.internal.util.Architecture.PPC
	at java.base/java.lang.Enum.valueOf(Enum.java:293)
	at java.base/jdk.internal.util.Architecture.valueOf(Architecture.java:39)
	at java.base/jdk.internal.util.Architecture.lookupByName(Architecture.java:99)
	at ArchTest.checkParams(ArchTest.java:120)
	at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103)
	at java.base/java.lang.reflect.Method.invoke(Method.java:580)


The test would verify that enum names are consistent with `os.arch`. Which would be `ppc`, based on build system pick. Therefore, we cannot do PPC32. I reverted the previous commit...
