Subject: 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.
