powerpc: Use the new post-link pass to check relocations Currently powerpc has to introduce a dependency on its default build target zImage in order to run a relocation check pass over the linked vmlinux. This is deficient because the check is not run if the plain vmlinux target is built, or if one of the other boot targets is built. Switch to using the kbuild post-link pass, added in commit fbe6e37dab97 ("kbuild: add arch specific post-link Makefile") in order to run this check. In future powerpc will use this to do more complicated operations, but initially using it for something simple is a good first step.

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: $ git clone linuxppc.git $ cd linuxppc.git $ 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 Equally running 'make distclean; make distclean' will trip the error case. Change the inclusion such that file not being found does not trigger an error.
