The one thing that is holding up the transition to arch/powerpc is lack
of people with access to the respective boards. If you have one board
that you care about, it would be good if you look into getting it moved
over. Tell us if you have problems doing so. It shouldn't be all that
hard any more, and if it is, maybe some documentation is missing.

You should simply install the headers with ARCH=powerc, even when the
kernel is built with ARCH=ppc. From the user space point of view, there
is only one set of headers.
