kernel: restore crtsavres.o to enable building external modules on powerpc
Fixes [YOCTO #1276] As of Linux kernel version 3.0.1, and much earlier, the make clean target removes arch/powerpc/lib/crtsavres.o. As this object is present in KBUILD_LDFLAGS_MODULE, it is required to build external modules, and should therefor not be removed by make clean. While I do not advocate fixing buggy kernels in the generic kernel classes, we should probably account for this one in kernel.bbclass as it affects such a long list of kernel versions.
