OK.
I dropped shared object feature and posted v2.

I hesitate to remove directory creation feature because:

[1] Kbuild is already used in some other projects. 
     Makefile.build, Makefile.lib, Makefile.host etc.
    are really useful build scripts.
    So, I think they should be kept generic enough
    for the maximum code re-use  in other projects.
    It is true that we no longer have hostprogs in Kernel where
    we need to create directories.
    But there might  be necessity in other projects.
    (At least, U-boot's hostprogs-y is depending on this feature.)
[2] For consistency.
     obj-y supports automatic directory creation.
     It is symmetrical that we support it for hostprogs-y.

In v2,  I simplified Makefile.host much more,
so please let me keep it.
