[ Upstream commit 1b1e38002648819c04773647d5242990e2824264 ]
crtsavres.o is linked to modules. However, as explained in commit d0e628cd817f ("kbuild: doc: clarify the difference between extra-y and always-y"), 'make modules' does not build extra-y.
For example, the following command fails:
$ make ARCH=powerpc LLVM=1 KBUILD_MODPOST_WARN=1 mrproper ps3_defconfig modules [snip] LD [M] arch/powerpc/platforms/cell/spufs/spufs.ko ld.lld: error: cannot open arch/powerpc/lib/crtsavres.o: No such file or directory make[3]: *** [scripts/Makefile.modfinal:56: arch/powerpc/platforms/cell/spufs/spufs.ko] Error 1 make[2]: *** [Makefile:1844: modules] Error 2 make[1]: *** [/home/masahiro/workspace/linux-kbuild/Makefile:350: __build_one_by_one] Error 2 make: *** [Makefile:234: __sub-make] Error 2
