NTFS (=m) uses hweight32(), but that function is only linked
into the kernel image if it is used inside the kernel image,
not in loadable modules. Let modules force HWEIGHT to be
built into the kernel image. Otherwise build fails:
Building modules, stage 2.
MODPOST 94 modules
WARNING: "hweight32" [fs/ntfs/ntfs.ko] undefined!
Yes, I'd certainly prefer for this to be more automated rather than
forced by each module that needs it.
Perhaps we should just put it in lib-y and remove CONFIG_GENERIC_HWEIGHT.

This will obviously not help in this case...
EXPORT_SYMBOL() in a lib-* is always a bug.
so I changed hweight.o to always be in obj-y instead of lib-y.
