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 for /, %/, %.ko
single targets for external modules. Create .tmp_versions in the
'prepare' target.
