[PATCH] powerpc: fix distclean with Makefile.postlink

Makefile.postlink always includes include/config/auto.conf, however
this file is not present in a clean kernel tree, causing make to fail:

arch/powerpc/Makefile.postlink:10: include/config/auto.conf: No such file or directory
make[1]: *** No rule to make target `include/config/auto.conf'.  Stop.
make: *** [vmlinuxclean] Error 2

Change the inclusion such that file not being found does not trigger
an error.

Fixes: f188d0524d7e ("powerpc: Use the new post-link pass to check relocations")

I can't reproduce this. What exact steps are you doing? And what version
of Make?

cheers

Start with a clean kernel tree and then
make distclean
arch/powerpc/Makefile.postlink:10: include/config/auto.conf: No such
file or directory
make[1]: *** No rule to make target `include/config/auto.conf'.  Stop.
make: *** [vmlinuxclean] Error 2

make --version
GNU Make 3.82

The fix is basically the same as:
6e5b95cdbd0e MIPS: Fix distclean with Makefile.postlink

Noticed it on the Fedora builds as well today.  This patch fixes it.
