Well, since uname -m returns "ppc", that is the arch we use. If
the Linux folks now want that to be powerpc, they should talk to
the glibc people I guess?

You can do:

 	 export ARCH=powerpc

to override this.

There is a "sanitize" bit in Makefile.inc:

# supply kernel-configuration ARCH defaults
ifeq ($(ARCH),)
ARCH := $(shell uname -m)
endif
# always sanitize $(ARCH)
ARCH := $(shell echo $(ARCH) | sed -e s/i.86/i386/ -e s/sun4u/sparc64/ -e s/arm.*/arm/ -e s/sa110/arm/ -e 's/ //g')

However, I am not sure how to deal with the *rename*. Since we should leave it
as "ppc" for some of the older kernels.
