[PATCH] lib: statically link find_last_bit

Currently, the only use of find_last_bit in the kernel is
setup_nr_cpu_ids which compiles only under CONFIG_SMP.
On uniprocessor machines the linker can't find it when
needed in a loadable module.

Kernel: arch/x86/boot/bzImage is ready (#5)
Building modules, stage 2.
MODPOST 515 modules
ERROR: "find_last_bit" [fs/nfs/nfs.ko] undefined!
