There is an additional fix you need to to, otherwise you will introduce 
a race condition.

This code:
ifneq (, $(findstring $(OPENJDK_TARGET_OS), solaris aix))

makes sure that libfontmanager is not built until libawt_xawt is present 
(otherwise linking will fail). With your patch, you should change this to

ifeq ($(OPENJDK_TARGET_OS), aix))
else ifeq ($(OPENJDK_TARGET_OS), solaris))

Otherwise, it looks good.

Erik and I have been discussing for some time to change the framework so 
this kind of dependencies will be automatically enforced, but somehow 
that idea always gets pushed down the priority slide. :(
