kbuild: support building individual files for external modules
Support building individual files when dealing with separate modules. So say you have a module named "foo" which consist of two .o files bar.o and fun.o. You can then do: make -C $KERNELSRC M=`pwd` bar.o make -C $KERNELSRC M=`pwd` bar.lst make -C $KERNELSRC M=`pwd` bar.i make -C $KERNELSRC M=`pwd` / <= will build all .o files and link foo.o make -C $KERNELSRC M=`pwd` foo.ko <= will build the module and do the modpost step to create foo.ko The above will also work if the external module is placed in a subdirectory using a hirachy of kbuild files. Thanks to Andreas Gruenbacher <agruen@suse.de> for initial feature request / bug report. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

Therefore a full kernel build needs to be executed to make

+--- 2.5 Building separate files for a module
+ It is possible to build single files which is part of a module.
+ This works equal for the kernel, a module and even for external
+ modules.
+ Examples (module foo.ko, consist of bar.o, baz.o):
+ make -C $KDIR M=`pwd` bar.lst
