If there are no builtin users of find_next_bit_le() and
find_next_zero_bit_le(), these functions are not present in the kernel
image, causing m68k allmodconfig to fail with:

This started to happen after commit 171d809df1896c1022f9778cd2788be6c255a7dc
("m68k: merge mmu and non-mmu bitops.h"), as m68k had its own inline
versions before.
commit 63e424c84429903c92a0f1e9654c31ccaf6694d0 ("arch: remove
CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT}") added find_last_bit.o to
obj-y (so it's always included), but find_next_bit.o to lib-y (so it gets
removed by the linker if there are no builtin users).

Sorry, I didn't notice it before, as m68k allmodconfig has been suffering
from too many build breakages (for which patches are available) lately.
Does it happen elsewhere, too?
