[PATCH] lib functions: always build hweight for loadable modules

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@oracle.com>

Always build hweight8/16/32/64() functions into the kernel so that
loadable modules may use them.

I didn't remove GENERIC_HWEIGHT since ALPHA_EV67, ia64, and some
variants of UltraSparc(64) provide their own hweight functions.

Fixes config/build problems with NTFS=m and JOYSTICK_ANALOG=m.

Kernel: arch/x86_64/boot/bzImage is ready  (#19)
  Building modules, stage 2.
  MODPOST 94 modules
WARNING: "hweight32" [fs/ntfs/ntfs.ko] undefined!
WARNING: "hweight16" [drivers/input/joystick/analog.ko] undefined!
WARNING: "hweight8" [drivers/input/joystick/analog.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
