kbuild: list sub-directories in ./Kbuild
Use the ordinary obj-y syntax to list subdirectories. Note1: Previously, the link order of lib-y depended on CONFIG_MODULES; lib-y was linked before drivers-y when CONFIG_MODULES=y, otherwise after drivers-y. This was a bug of commit 7273ad2b08f8 ("kbuild: link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y"), but it was not a big deal after all. Now, all objects listed in lib-y are linked last, irrespective of CONFIG_MODULES. Note2: Finally, the single target build in arch/*/lib/ works correctly. There was a bug report about this.
