kbuild: fix single target build for external module
Building a single target in an external module fails due to missing .tmp_versions directory. For example, $ make -C /lib/modules/$(uname -r)/build M=$PWD foo.o will fail in the following way: CC [M] /home/masahiro/foo/foo.o /bin/sh: 1: cannot create /home/masahiro/foo/.tmp_versions/foo.mod: Directory nonexistent This is because $(cmd_crmodverdir) is executed only before building /, %/, %.ko single targets of external modules. Create .tmp_versions in the 'prepare' target. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
