Subject: [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")
