attached an ugly and hacky patch which allows me to build 2.6.15 on powerpc.

thanks
hi Manoj, about this issue, i attach a quick and dirty patch, which at least
pinpoints the two places where we have an issue on powerpc. The main point is
that on powerpc the debian arch is 'powerpc', while the kernel arch can be
either ppc, ppc64 or powerpc, depending on the version and the choices made.
There is some code, with some funny mention of powerpc64 i don't know where it
comes from, that sets KERNEL_CROSS if the debian architecture is different
than the kernel arch, which obviously is a wrong assumption in this case, and
the same errors shows in the dpkg-architecture call.
I would say that the best solution here is to have some mapping between the
powerpc arches (ppc, ppc64, powerpc, powerpc32 and powerpc64) to the debian
powerpc (and powerpc64) arch, none of them needs a cross compiler since we
have a real biarch toolchain now.
Hoping to see a real fix in the archive soon, which would allow me to build
the 2.6.15-rc (and 2.6.15 once it is released, which will be RSN hopefully),
on powerpc.
The first hunk of this patch sets ARCH=ppc again for 32bit, i am not sure i
will be going this way or not finally, since upstream recomends me to go with
ARCH=powerpc on 32bit only for 2.6.16 and later.
Friendly,
Sven Luther
