I think this test setting is weird.

With the following error, it is pointless to test this.

>   Makefile:499: arch/powerpc64/Makefile: No such file or directory


arch/powerpc64/ does not exist in the first place.


If you really want to give ARCH=powerpc64,
you need to add something like follows in the top Makefile
(but I doubt this is the right thing to do)

ifeq ($(ARCH),powerpc64)
       SRCARCH := powerpc
endif


Could you check your test setting, please?
