Some comments:
In make/copy/Copy-java.base.gmk:
+ifneq ($(findstring $(OPENJDK_TARGET_OS), aix),)

The findstring construct is hard to read and only needed when we test 
more than one OS. Please rewrite as a single ifeq test for aix.

In GensrcCLDR.gmk:
I don't understand the CLDR_WINTZMAPPINGS file? There's no rule to 
generate it, there's just a dependency..?

The removal of the duplicate "common", that seems like a separate bug fix?
