Subject: m68knommu: fix build error due to the lack of find_next_bit_le()
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>

m68knommu can't build ext4, udf, and ocfs2 due to the lack of
find_next_bit_le().

This implements find_next_bit_le() on m68knommu by duplicating the generic
find_next_bit_le() in lib/find_next_bit.c.
